MIC2951

150 mA Low-Dropout Voltage Regulator

Features

General Description

• High Accuracy 3.3V, 4.85V, or 5V, Guaranteed

150 mA Output

The MIC2951 is a “bulletproof” micropower voltage

regulator with very low dropout voltage (typically 40 mV

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

quiescent current. Like its predecessor, the LP2951,

the quiescent current of the MIC2951 increases only

slightly in dropout, which prolongs the battery life. The

MIC2951 is pin-for-pin compatible with the LP2951, but

offers a lower dropout, lower quiescent current, reverse

battery, and automotive load dump protection.

• Extremely Low Quiescent Current

• Low-Dropout Voltage

• Extremely Tight Load and Line Regulation

• Very Low Temperature Coefficient

• Use as Regulator or Reference

• Needs Only 1.5 µF for Stability

• Current and Thermal Limiting

The key additional features and protection offered

include higher output current (150 mA), 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).

• Unregulated DC Input Can Withstand –20V

Reverse Battery and +60V Positive Transients

• Error Flag Warns of Output Dropout

• Logic-Controlled Electronic Shutdown

• Output Programmable from 1.24 to 29V

The plastic DIP, SOIC, and MSOP versions offer

system functions such as programmable output

voltage and logic controlled shutdown.

Applications

• Automotive Electronics

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

• Voltage Reference

• Avionics

used as

a power-on reset. A logic-compatible

• Cellular Telephones

• Battery Powered Equipment

• SMPS Post-Regulator

• High Efficiency Linear Power Supplies

shutdown input is also available which enables the

regulator to be switched on and off. This part may also

be pin-strapped for a 5V output, or programmed from

1.24V to 29V with the use of two external resistors.

The MIC2951 is available as an -02 or -03 version.

Package Type

The MIC2951 has a tight initial tolerance (0.5% typical),

a very low output voltage temperature coefﬁcient,

which allows use as a low-power voltage reference,

and extremely good load and line regulation (0.04%

typical). This greatly reduces the error in the overall

circuit and is the result of careful design techniques and

process control.
