Volver a Nisshinbo

Nisshinbo RP120Z LDO Regulators

Nisshinbo RP120Z LDO (Low-Dropout) Regulators are designed to operate at an input voltage as low as 0.768V. The RP120Z LDO Regulators use an internal low on-resistance NMOS transistor as a driver. The VBIAS pin provides the higher supply necessary for the LDO circuitry while the output current comes directly from the VIN input for high-efficiency regulation. These devices feature a high Power Supply Rejection Ratio (PSRR), high output current, and fast response characteristics.

The Nisshinbo RP120Z LDO Regulators are offered in a compact 1.2mm x 0.8mm Wafer Level Chip Scale Package (WLCSP), ideal for space-constrained applications.
