MIC37139

MIC37139 1.5A, Low-Voltage µCap LDO Regulator General Description The Micrel MIC37139 is a 1.5A low-dropout linear voltage regulator that provides a low-voltage, high-current output with a minimum of external components. It offers high precision, ultra-low dropout (500mV overtemperature), and low ground current. The MIC37139 operates from an input of 2.25V to 6.0V. It is designed for a wide variety of applications including digital circuits requiring low-voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). It is available in a fixed output voltage of 1.8V, and as low as 1.5V. Features of the MIC37139 LDO include thermal and current-limit protection, and reverse-current and reversebattery protection. It’s junction temperature range of the is from –40°C to +125°C. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
