MIC2950*/2951

150mA Low-Dropout Voltage Regulator

General Description

Features

The MIC2950 and MIC2951 are “bulletproof” micropower

voltage regulators with very low dropout voltage (typically

40mV at light loads and 250mV at 100mA), and very low

quiescent current. Like their predecessors, the LP2950 and

LP2951, the quiescent current of the MIC2950/MIC2951

increases only slightly in dropout, thus pro-longing battery

life. The MIC2950/MIC2951 are pin for pin compatible with

the LP2950/LP2951, but offer lower dropout, lower

quiescent current, reverse battery, and automotive load

dump protection.

• High accuracy 3.3, 4.85, or 5V, guaranteed 150mA

output

• Extremely low quiescent current

• Low-dropout voltage

• Extremely tight load and line regulation

• Very low temperature coefficient

• Use as regulator or reference

• Needs only 1.5µF for stability

• Current and thermal limiting

• Unregulated DC input can withstand –20V reverse

The key additional features and protection offered include

higher output current (150mA), positive transient protection

for up to 60V (load dump), and the ability to survive an

unregulated input voltage transient of –20V below ground

(reverse battery).

battery and +60V positive transients

MIC2951 Version Only

• Error flag warns of output dropout

• Logic-controlled electronic shutdown

• Output programmable from 1.24 to 29V

The plastic DIP and SOIC versions offer additional system

functions such as programmable output voltage and logic

controlled shutdown. The 3-pin TO-92 MIC2950 is pin-

compatible with the older 5V regulators.

Applications

These system functions also include an error ﬂag output

that warns of a low output voltage, which is often due to

failing batteries on the input. This may also be used as a

power-on reset. A logic-compatible shutdown input is also

available which enables the regulator to be switched on and

off. This part may also be pin-strapped for a 5 V output, or

programmed from 1.24 V to 29 V with the use of two

external resistors.

• Automotive electronics

• Voltage reference

• Avionics

• Cellular telephones

• Battery powered equipment

• SMPS post-regulator

• High efficiency linear power supplies
