mcp1701a ds21991b-page 10 ? 2006 microchip technology inc. 4.0 detailed description the mcp1701a is a low-quiescent current, precision, fixed-output voltage ldo. unlike bipolar regulators, the mcp1701a supply current does not increase proportionally with load current. 4.1 output capacitor a minimum of 1 f output capacitor is required. the output capacitor should have an 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 reject ion and transient response. care should be taken when increasing c out to ensure that the input impedance is not high enough to cause high input impedance oscillation. 4.2 input capacitor 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. 4.3 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. figure 4-1: mcp1701a block diagram. v in v out gnd short circuit protection voltage reference + ?
? 2006 microchip technology inc. ds21991b-page 11 mcp1701a 5.0 thermal considerations 5.1 power dissipation the amount of power dissipa ted 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. equation 5-1: the internal power dissipation, as a result of the bias current for the ldo internal reference and error amplifier, is calculated as shown in equation 5-2. equation 5-2: the total internal power dissipation is the sum of p d (pass device) and p d (bias). equation 5-3: for the mcp1701a, the internal quiescent bias current is so low (2 a, typ.) that the p d (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. equation 5-4: to determine the junction te mperature of the device, the thermal resistance from junction-to-ambient must be known. the 3-pin sot-23 thermal resistance from junction-to-air (r ja ) is estimated to be approximately 335 c/w. the sot-89 r ja is estimated to be approximately 52 c/w when mounted on 1 square inch of copper. the r ja will vary with ph ysical 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 5-5: junction temperature ? sot-23 example: equation 5-6: junction temperature ? sot-89 example: given: v in = 3.3v to 4.1v v out =3.0v 2% i out = 1 ma to 100 ma t amax = 55c p max = (4.1v ?
