MIC2215

Triple High PSRR, Low Noise

Cap LDO

General Description

The MIC2215 is a high performance, triple LDO voltage

regulator, with each regulator capable of providing 250mA

continuous output current.

Ideal for battery operated applications, the MIC2215 offers

1% initial accuracy, extremely low dropout voltage (100mV@

150mA), and low ground current at light load (typically 110µA

per regulator). Equipped with a noise bypass pin and featur-

ing very high power supply ripple rejection (PSRR) of up to

80dB, the MIC2215 provides the lowest noise and highest

efficiency solution for RF applications in portable electronics

such as cellular phones and wireless LAN applications.

Equipped with TTL logic-compatible enable pins, each of the

regulators in the MIC2215 can be put into a zero current off

mode where the supply current is much less than 1µA when

all the regulators are disabled. The MIC2215 is a

µCap

design, which enables a stable output with small ceramic

output capacitors, reducing both cost and required board

space for output bypassing.

The MIC2215 is available in the miniature 16-pin, 4mm

4mm

MLF™ package.
