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 featuring very high

(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
