GM6251
300mA ULTRA LOW DROPOUT
POSITIVE VOLTAGE REGULATOR
Description
GM6251 combines high accuracy with very low
power consumption, and provides high output
current even when the application requires
extremely low input-output voltage dropout.
GM6251 includes a precision voltage reference,
an error correction circuit, over-temperature
protection, and a current limited output driver.
Fast transient response to load variations
provides excellent stability under dynamic loads.
GM6251 comes in SOT-25 (150mW), TO92 and
SOT-89 (500mW).
