The input operating range is specified up to 10V, making it ideal for lithium-ion (one or two cells), 9V alkaline and other two and three primary cell battery-powered applications. The MCP1701 is capable of delivering 250 mA with an input-to-output voltage differential (dropout voltage) of 650 mV. The low dropout voltage extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum VIN - VOUT differentials. The MCP1701 has a tight tolerance output voltage regulation of 0.5% (typical) and very good line regulation at 0.2%. The LDO output is stable when using only 1 F of output capacitance of either tantalum or aluminum-electrolytic style capacitors. The MCP1701 LDO also incorporates short-circuit protection to ensure maximum reliability. Package options include the 3-Pin SOT-23A, 3-Pin SOT-89 and 3-Pin TO-92. 2 A Low Dropout Positive Voltage Regulator Applications * * * * * * * * * * * * Battery-Powered Devices Battery-Powered Alarm Circuits Smoke Detectors CO2 Detectors Smart Battery Packs PDAs Low Quiescent Current Voltage Reference Cameras and Portable Video Equipment Pagers and Cellular Phones Solar-Powered Instruments Consumer Products Microcontroller Power Package Types 3-Pin SOT-23A VIN 3 MCP1701 1 GND 2 VOUT 3-Pin TO-92 123 MCP1701 1 2 3 3-Pin SOT-89 VIN Related Literature * AN765, "Using Microchip's Micropower LDOs", DS00765, Microchip Technology Inc., 2002 * AN766, "Pin-Compatible CMOS Upgrades to Bipolar LDOs", DS00766, Microchip Technology Inc., 2002 GND VIN VOUT Bottom View GND VIN VOUT Note: The 3-Pin SOT-23A is equivalent to the EIAJ SC-59. 2004 Microchip Technology Inc.

TABLE 3-1: Pin No. SOT-23A 1 2 3 PIN FUNCTION TABLE Pin No. SOT-89 1 3 2 Pin No. TO-92 1 3 2 Name GND VOUT VIN Ground terminal Regulated voltage output Unregulated supply input Function 3.1 Ground Terminal (GND) 3.3 Unregulated Supply Input (VIN) Regulator ground. Tie GND to the negative side of both the output and the input capacitor. Only the LDO bias current (2 A, typical) flows out of this pin, as there is no high current. The LDO output regulation is referenced to this pin. Minimize voltage drops between this pin and the negative side of the load. 3.2 Regulated Voltage Output (VOUT) Connect VOUT to the positive side of the load and the positive terminal of the output capacitor. The positive side of the output capacitor should be located as close as possible to the LDO VOUT pin. The current flowing out of this pin is equal to the DC load current. Connect the input supply voltage and the positive side of the input capacitor to VIN. Like all low dropout linear regulators, low source impedance is necessary for the stable operation of the LDO. The amount of capacitance required to ensure low source impedance will depend on the proximity of the input source capacitors or battery type. The input capacitor should be located as close as possible to the VIN pin. For most applications, 1 F of capacitance will ensure stable operation of the LDO circuit. For applications that have load currents below 100 mA, the input capacitance requirement can be lowered. The type of capacitor used can be ceramic, tantalum or aluminum-electrolytic. The low ESR characteristics of the ceramic will yield better noise and PSRR performance at high frequencies. The current flow into this pin is equal to the DC load current, plus the LDO bias current (2 A, typical). 2004 Microchip Technology Inc. DS21874A-page 9 MCP1701 4.0 DETAILED DESCRIPTION 4.2 Input Capacitor The MCP1701 is a low quiescent current, precision, fixed-output voltage LDO. Unlike bipolar regulators, the MCP1701 supply current does not increase proportionally with load current. A 1 F input capacitor is recommended for most applications when the input impedance is on the order of 10. Larger input capacitance may be required for stability when operating from a battery input, or if there is a large distance from the input source to the LDO. When large values of output capacitance are used, the input capacitance should be increased to prevent high source impedance oscillations. 4.1 Output Capacitor A minimum of 1 F output capacitor is required. The output capacitor should have an effective series resistance (esr) greater than 0.1 and less than 5, plus a resonant frequency above 1 MHz. Larger output capacitors can be used to improve supply noise rejection and transient response. Care should be taken when increasing COUT to ensure that the input impedance is not high enough to cause high input impedance oscillation. 4.3 Overcurrent The MCP1701 internal circuitry monitors the amount of current flowing through the P-channel pass transistor. In the event of a short-circuit or excessive output current, the MCP1701 will act to limit the output current.

MCP1701 5.0 5.1 THERMAL CONSIDERATIONS Power Dissipation The amount of power dissipated internal to the LDO linear regulator is the sum of the power dissipation within the linear pass device (P-channel MOSFET) and the quiescent current required to bias the internal reference and error amplifier. The internal linear pass device power dissipation is calculated as shown in Equation 5-1. To determine the junction temperature of the device, the thermal resistance from junction-to-ambient must be known. The 3-pin SOT-23 thermal resistance from junction-to-air (RJA) is estimated to be approximately 335C/W. The SOT-89 RJA is estimated to be approximately 52C/W when mounted on 1 square inch of copper. For the TO-92, RJA is estimated to be 131.9C/W. The RJA will vary with physical layout, airflow and other application-specific conditions. The device junction temperature is determined by calculating the junction temperature rise above ambient, then adding the rise to the ambient temperature. EQUATION 5-1: PD (Pass Device) = (VIN - VOUT) x IOUT The internal power dissipation, which is due to the bias current for the LDO internal reference and error amplifier, is calculated as shown in Equation 5-2. EQUATION 5-5: JUNCTION TEMPERATURE - SOT-23 EXAMPLE: EQUATION 5-2: PD (Bias) = VIN x IGND The total internal power dissipation is the sum of PD (Pass Device) and PD (Bias). T J = P D MAX x R JA + T A T J = 116.0 milliwatts x 335C/W + 55C T J = 93.9C EQUATION 5-6: EQUATION 5-3: PTOTAL = PD (Pass Device) + PD (Bias) For the MCP1701, the internal quiescent bias current is so low (2 A, typical) that the PD (Bias) term of the power dissipation equation can be ignored. The maximum power dissipation can be estimated by using the maximum input voltage and the minimum output voltage to obtain a maximum voltage differential between input and output. The next step would be to multiply the maximum voltage differential by the maximum output current. JUNCTION TEMPERATURE - SOT-89 EXAMPLE: T J = 116.0 milliwatts x 52C/W + 55C T J = 61C EQUATION 5-7: JUNCTION TEMPERATURE - TO-92 EXAMPLE: T J = 116.0 milliwatts x 131.9C/W + 55C T J = 70.3C EQUATION 5-4: PD = (VINMAX - VOUTMIN) x IOUTMAX Given: VIN = 3.3V to 4.1V VOUT = 3.0V 2% IOUT = 1 mA to 100 mA TAMAX = 55C PMAX = (4.1V - (3.0V x 0.98)) x 100 mA PMAX = 116.0 milliwatts 2004 Microchip Technology Inc.
