MIC94310

200mA LDO with

Ripple Blocker™ Technology

General Description

Features

The MIC94310 Ripple Blocker™ is a monolithic integrated

circuit that provides low-frequency ripple attenuation

(switching noise rejection) to a regulated output voltage.

This is important for applications where a DC/DC switching

converter is required to lower or raise a battery voltage but

where switching noise cannot be tolerated by sensitive

downstream circuits such as in RF applications. The

MIC94310 maintains high power supply ripple rejection

(PSRR) with input voltages operating near the output

voltage level to improve overall system efficiency. A low-

voltage logic enable pin facilitates ON/OFF control at

typical GPIO voltage levels.

• 1.8V to 3.6V input voltage range

• Active noise rejection over a wide frequency band

−

>50dB from 10Hz to 10MHz at 200mA load

• Rated to 200mA output current

• Fixed output voltages

• Current-limit and thermal-limit protected

• Ultra-small 0.88mm x 0.88mm 4-ball CSP

• 1.2mm x 1.6mm, 4-pin Thin MLF^®

• Logic-controlled enable pin

• −40°C to +125°C junction temperature range

The MIC94310 operates from an input voltage of 1.8V to

3.6V.

Applications

Packaged in a 0.88mm x 0.88mm 4-ball CSP or a 4-pin

1.2mm x 1.6mm Thin MLF^®, the MIC94310 has a junction

operating temperature range of –40°C to +125°C.
