250 mA LOW-DROPOUT VOLTAGE
REGULATOR
DESCRIPTION
The UTC M2950/2951 is a monolithic integrated voltage
regulator with low dropout voltage, and low quiescent current.
It includes many features that suitable for different
applications. Available in 3-pin TO-92, DIP-8 and SOP-8
packages.
FEATURES

Note 1: Additional conditions for 8-pin versions are feedback tied to 5V Tap an Output tied to Output Sense
(Vout=5V) and Vshutdown<=0.8V.
Note 2:Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV
below its nominal value measured at 1V differential.
Note 3:Comparator thresholds are expressed in terms of percentage value of voltage output.
Note 4:Vref≤Vout≤(Vin-1V), 2.3V≤Vin≤30V, 100µA≤IL≤250mA, TJ≤TJMAX
