MIC2215
Triple High PSRR, Low Noise Cap LDO
General Description Features
The MIC2215 is a high performance, triple LDO voltage
Input voltage range: +2.25V to +5.5V
regulator, with each regulator capable of providing 250mA
70dB PSRR
continuous output current.
Stable with ceramic output capacitor
Ideal for battery operated applications, the MIC2215 offers
High output accuracy:
1% initial accuracy, extremely low dropout voltage (100mV
1.0% initial accuracy
@ 150mA), and low ground current at light load (typically
2.0% over temperature
110A per regulator). Equipped with a noise bypass pin
and featuring very high power supply ripple rejection
Low dropout voltage of 100mV@150mA
(PSRR) of up to 80dB, the MIC2215 provides the lowest
Low quiescent current:110A per regulator
noise and highest efficiency solution for RF applications in
Fast turn-on time:30s
portable electronics such as cellular phones and wireless
Zero off-mode current
LAN applications.
Thermal shutdown protection
Equipped with TTL logic-compatible enable pins, each of
the regulators in the MIC2215 can be put into a zero Current-limit protection
current off mode where the supply current is much less
Tiny 16-pin (4mm 4mm) MLF package
than 1A when all the regulators are disabled. The
MIC2215 is a Cap design, which enables a stable output

with small ceramic output capacitors, reducing both cost
and required board space for output bypassing.
Cellular phones
The MIC2215 is available in the miniature 16-pin,
PCs and peripherals
(4mm4mm) MLF package.
