AP7173 Datasheet | Diodes Incorporated

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: 165m V 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 pound (No Br, Sb) - Lead-free finish/ Ro HS pliant (Note 1) Pin Assignments ( Top View ) IN 1 IN 2 PG 3 VCC 4 EN 5 10 OUT 9 OUT 8 FB 7 SS 6 GND DFN3030-10 (Top View) IN 1 PG 2 8 OUT 7 FB 6 SS EN 4 5 GND Applications SO-8EP - PCs, Servers, Modems, and Set-Top-Boxes - FPGA Applications - DSP Core and I/O Voltages - Post-Regulation Applications - Applications With Sequencing Requirements Note: 1.
