DATASHEET EL7531 Monolithic 1A Step-Down Regulator with Low Quiescent Current FN7428 Rev 10.00 December 10, 2015 The EL7531 is a synchronous, integrated FET 1A step-down regulator with internal compensation. It operates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider. The EL7531 features automatic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1.4MHz and can be synchronized up to 12MHz. The typical no load quiescent current is only 120µA. Additional features include a Power-Good output, <1µA shut-down current, short-circuit protection, and over-temperature protection.
