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 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.
