Overview
RP120 Series Low Input / Output 1.
5 A Low Dropout Regulator OVERVIEW No.
EA-585-230706 The RP120 is a very low dropout regulator which operates from input voltage as low as 0.
768 V (@VSET = 0.
6 V, VBIAS = 3.
3 V, IOUT = 1.
5 A).
The LDO uses an internal low on-resistance (67 mΩ @VSET = 0.
6 V, VBIAS = 3.
3 V, IOUT = 1 A) NMOS transistor as the 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.
KEY BENEFITS  High PSRR, high output current, and fast response characteristics.
 Suitable for sensitive sensors, high-quality audio, and RF devices.
 Very small WLCSP package (1.
2 mm x 0.
8 mm x 0.
29 mm).
