ME6212C12M5G high speed LDO regulators and PSRR, low noise 

1.2V LDO, marking CA**

The ME6212C12M5G is a highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the ME6212 series is ideal for today’s cutting-edge mobile phone. Internally the ME6212 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The ME6212’s current limiters' foldback circuit also operates as short protection for the output current limiter. the output pin, is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The CE function allows the output of the regulator to be turned off, resulting in greatly reduced power consumption.

Typical Application:

Mobile phones

Cordless phones, radio communication equipment

Portable games

Cameras, Video cameras

Reference voltage sources

Battery-powered equipment
