regulator with low dropout voltage, and low quiescent current. It
includes many features that suitable for different applications.
FEATURES
* Fixed output versions, 2.5V, 3V, 3.3V, 3.6V and 5V, are
available.
* Extremely low quiescent current and dropout voltage.
* Extremely tight load and line regulation.
* Current and thermal limiting.
* Very low temperature coefficient.
Lead-free:
M2950-XX/2951L
* Logic controlled shutdown and err flog available for 8 pin
package.
Halogen-free: M2950-XX/2951G
* Output voltage programmable for M2951

(VOUT=5V) and VSHDN≦0.8V.
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.
3. Comparator thresholds are expressed in terms of percentage value of voltage output.
