AP7173

AP7173 1.5A LOW DROPOUT LINEAR REGULATOR WITH PROGRAMMABLE SOFT-START Description The AP7173 is a 1.5A low-dropout (LDO) linear regulator that features a user-programmable soft-start, an enable input and a power-good output. The soft-start reduces inrush current of the load capacitors and minimizes stress on the input power source during startup. The enable input and power-good output allow users to configure power management solutions that can meet the sequencing requirements of FPGAs, DSPs, and other applications with different start-up and power-down requirements. The AP7173 is stable with any type of output capacitor of 2.2µF or more. A precision reference and feedback control deliver 2% accuracy over load, line, and operating temperature ranges. The AP7173 is available in both DFN3030-10 and SO-8EP packages. Features ● Low VIN and wide VIN range: 1.0V to 5.5V ● Bias voltage (VVCC) range: 2.7V to 5.5V ● Low VOUT range: 0.8V to 3.3V ● Low dropout: 165mV typical at 1.5A, VVCC = 5V ● 2% accuracy over line, load and temperature range ● Power-Good (PG) output for supply monitoring and for sequencing of other supplies ● Programmable soft-start provides linear voltage startup ● Bias supply permits low VIN operation with good transient response ● Stable with any output capacitor ≥ 2.2µF ● DFN3030-10 and SO-8EP: available in “Green” molding compound (No Br, Sb) ● Lead-free finish/ RoHS Compliant (Note 1) Pin Assignments ( Top View ) IN 1 IN 2 PG 3 VCC 4 EN 5 10 OUT 9 OUT 8 FB...
