MIC5252

150 mA High PSRR, Low Noise μCap CMOS LDO

Features

General Description

• Input Voltage Range: 2.7V to 6.0V

• PSRR = 50 dB @ V_O+ 0.3V

The MIC5252 is an efficient, precise CMOS voltage

regulator optimized for ultra low-noise applications. It

offers 1% initial accuracy, extremely low dropout

voltage (135 mV at 150 mA) and low ground current

(typically 90μA). The MIC5252 provides a very

low-noise output, ideal for RF applications where a

clean voltage source is required. The MIC5252 has a

high PSRR even at low supply voltages, critical for

battery operated electronics. A noise bypass pin is also

available for further reduction of output noise.

• Ultra-Low Output Noise: 30 μV_RMS

• Stability with Ceramic Output Capacitors

• Ultra-Low Dropout: 135 mV @ 150 mA

• High Output Accuracy:

- 1.0% Initial Accuracy

- 2.0% over Temperature

• Low Quiescent Current: 90μA

• Tight Load and Line Regulation

• TTL Logic-Controlled Enable Input

• “Zero” Off-Mode Current

Designed specifically for handheld and battery-

powered devices, the MIC5252 provides a TTL

logic-compatible enable pin. When disabled, power

consumption drops nearly to zero.

• Thermal Shutdown and Current Limit Protection

The MIC5252 also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, which is critical in

handheld wireless devices.

Applications

• Cellular Phones and Pagers

• Cellular Accessories

Key features include current limit, thermal shutdown,

faster transient response, and an active clamp to speed

up device turn-off. The MIC5252 is available in the

6-lead 2 mm × 2 mm VDFN package and the 5-Lead

SOT-23 package in a wide range of output voltages.

• Battery-Powered Equipment

• Laptop, Notebook, and Palmtop Computers

• Consumer/Personal Electronics
