5F03N-Rev. F002

Fixed Voltage Regulator

Adjustable Voltage Regulator

Notes：

1.) C1 need if device is far from filter capacitors

VOUT=VREF x(1+R2/R1)+IADJxR2

2.) C2 minimum value required for stability.

GENERAL DESCRIPTION

FEATURES

The EC50117S series of positive adjustable and fixed

regulators are designed to provide 1A with high efficiency.

All internal circuitry is designed to operate down to 1.4V

input to output differential. On-chip trimming adjusts the

reference voltage to 1%. Current limit the typical value of

1.5A allows to minimizing the stress on both the regulator

and the power source circuitry under overload conditions.

● Adjustable or Fixed Voltage.

● Output current of 1A.

●Low Dropout Voltage 1.2V(Typ.) at 1A Output Current.

● 0.04% Line Regulation

● 0.2 % Load Regulation

● 100% Thermal Limit Burn-In

● Fast Transient Response

● Current-Limit : 1A Typ. at T

J = 25°C

● On-Chip Thermal Limiting : 150°C Typ.

Applications

● Efficiency Linear Regulators

● Post Regulators for Switching Supplies

● Adjustable Power Supply
