MICRONE ME6219C25M5G

The ME6219 series are high-precision, low-noise, ultra-fast response LDO linear regulators fabricated using CMOS process technology. These regulators integrate a fixed reference voltage source, error correction circuit, current limiting circuit, phase compensation circuit, and a low on-resistance MOSFET to achieve high ripple rejection, low output noise, and ultra-fast response low dropout performance. The ME6219 is compatible with ceramic capacitors smaller than tantalum capacitors and does not require a 0.1μF bypass capacitor, saving more board space. Its excellent high-speed response characteristics handle load current fluctuations effectively, making it particularly suitable for handheld and RF products. The output can be shut down by controlling the CE pin on the chip, with shutdown current consumption below 1μA.
