EC50117S

1A Low Dropout Positive Voltage Regulator

GENERAL DESCRIPTION

FEATURES

●

Adjustable or Fixed Voltage.

● Output current of 1A.

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

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.

●

● 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.

PIN ASSIGNMENT

Package: SOT223-3L

Applications

● Efficiency Linear Regulators

● Post Regulators for Switching Supplies

● Adjustable Power Supply

Typical Application Circuits

Fixed Voltage Regulator

Adjustable Voltage Regulator

Notes：

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

2.) C2 minimum value required for stability.

VOUT=V_REFx(1+R2/R1)+I_ADJxR2
