RP123x Series

250 mA Low Noise and Low Supply Current LDO Regulator

No.EA-508-190326

OVERVIEW

The RP123x is a LDO regulator that provides low output noise, high ripple rejection and fast response

characteristics, achieved by low supply current. This device is suitable not only for noise-sensitive

applications such as high-performance analog circuits, but also for various applications.

KEY BENEFITS

 Achieves Low Noise, High PSRR and Fast Response.

 Provides Saving Space by Adopting of 4-pin Small Package without Noise Bypass Capacitor.

 Provides Long-Duration of Operation for Battery-powered Equipment by Low Supply Current of 9.5 µA

(Typ.), despite the low-noise LDO.

KEY SPECIFICATIONS

 Input Voltage Range (Max.Rating):1.9 V to 5.5 V (6.0 V)

 Output Voltage Range:

 Output Voltage Accuracy:

 Supply Current:

1.2 V to 4.8 V (0.1 V step)

±0.8% (V_SET≥ 1.8 V, Ta = 25°C)

Typ. 9.5 µA

 Output Noise:

Typ. 8 µVrms (I_OUT= 250 mA)

 Ripple Rejection:

Typ. 90 dB (f = 1kHz)

Typ. 85 dB (f = 10kHz)

Typ. 65 dB (f = 100kHz)

 Dropout Voltage:

Typ. 0.090 V (I_OUT= 250 mA, V_SET= 2.8 V, RP123Z)

Typ. 0.105 V (I_OUT= 250 mA, V_SET= 2.8 V, RP123K)

Thermal Shutdown Protection (Detection Temp. Typ.165°C)

Inrush Current Limit at Typ.150 mA for appr.700μs period after startup

1.0 µF or more (No Need of Noise Bypass Capacitor)

 Protection Features:

 Ceramic Capacitor (C_IN, C_OUT):
