MIC37300/01/02/03 3.0A, Low-Voltage Cap LDO Regulator General Description Features The Micrel MIC37300/01/02/03 is a 3.0A low-dropout 3.0A minimum guaranteed output current linear voltage regulator that provides a low voltage, high 500mV maximum dropout voltage over temperature current output with a minimum number of external Ideal for 3.0V to 2.5V conversion components. It offers high precision, ultra-low dropout Ideal for 2.5V to 1.8V, 1.65V, or 1.5V conversion (500mV over temperature), and low ground current. Stable with ceramic or tantalum capacitor The MIC37300/01/02/03 operates from an input of 2.25V Wide input voltage range to 6.0V. It is designed to drive digital circuits requiring low- V : 2.25V to 6.0V voltage at high currents (i.e., PLDs, DSP, microcontroller, IN etc.). It is available in xed and adjustable output voltages. +1.0% initial output tolerance Fixed voltages include 1.5V, 1.8V, 2.5V, and 3.3V. The Fixed and adjustable output voltages: adjustable version is capable of 1.24V to 5.5V. MIC37300: 3-pin S-Pak xed voltages Features of the MIC37300/01/02/03 LDO include thermal MIC37301: 5-pin S-Pak or 8-pin ePad SOIC xed and current-limit protection, and reverse-current protection. voltages with ag Logic enable and error ag pins are available on the 5-pin MIC37302: 5-pin adjustable voltage version. MIC37303: 8-pin ePad SOIC, DFN adjustable voltage Junction temperature range of the MIC37300/01/02/03 is with flag from 40C to +125C. Excellent line and load regulation specications For applications requiring input voltage greater than 6.0V, Thermal-shutdown and current-limit protection see the MIC3910x, MIC3915x, MIC3930x, and MIC3950x Reverse-leakage protection LDOs.
