| 5.0A Low Dropout Voltage Regulator Adjustable CORPORATION CLM2850 FEATURES PRODUCT DESCRIPTION The Calogic CLM2850 is a low power 5A adjustable voltage regulator that is very easy to use. It requires only 2 external resistors to set the output voltage. This device is an excellent choice for use in powering Intel microprocessors to convert from +5V to 3.3V supplies and as a post regulator for switching supplies applications. TM * Adjustable Output Down to 1.2V * Output Current of 5A * Low Dropout Voltage and Line Regulation * Extremely Tight Load * Current and Thermal Limiting * Standard 3-Terminal Low Cost TO-220 * Similar to Industry Standard LT1084 * Powering Intel Pentium P from +5V Supplies PC Supplies * Power Post-Regulator * SMPS * High Efficiency "Green" Computer Systems * High Efficiency Linear Power Supplies * Portable Instrumentation * Constant Current Regulators * Adjustable Power Supplies * Battery Chargers TM TM APPLICATIONS The CLM2850 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The IQ of this device flows into the load which increases efficiency. The CLM2850 is offered in a 3-pin TO-220 package compatible with older 3 terminal regulators. For a 3A low dropout regulator refer to the CLM2830 data sheet.
