GR GR6219B252MR

The GR6219xx series are high-precision, low-noise, fast-response LDO linear regulators fabricated using CMOS process. These regulators integrate a fixed reference voltage, error correction circuit, current limiting circuit, phase compensation circuit, and a low on-resistance MOSFET, achieving high ripple rejection, low output noise, and fast-response low-dropout performance.

The GR6219xx series is compatible with ceramic capacitors, which are smaller in size than tantalum capacitors, and does not require a 0.1μF bypass capacitor, enabling further space savings and cost reduction. With high-precision output stability and fast transient response to handle load current fluctuations, it is especially suitable for handheld devices and RF products.

By controlling the CE pin on the chip, the output can be shut down. The quiescent current after shutdown is only 0.1μA (Typ), significantly reducing power consumption.
