MIC2215
Triple High PSRR, Low Noise
μ
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 110
μ
A
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 1
μ
A when
all the regulators are disabled. The MIC2215 is a
μ
Cap
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.
