The APL1087R is a low dropout three-terminal adjustable regulator with 0.8A output current capability. It has been optimized to achieve lower dropout voltage and faster transient response, which is critical for low voltage applications. The device is available in an adjustable version and fixed output voltages of 1.8V, 2.5V, and 3.3V. The output voltage range is from 1.25V to 7.15V with an input supply below 9V. The dropout voltage is guaranteed to be a maximum of 1.45V at 0.5A. The current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection.
The APL1087R is an 800 mA low‑dropout positive adjustable regulator from ANPEC, offering both adjustable (1.25‑7.15 V) and fixed (1.8 V, 2.5 V, 3.3 V) output options. It provides fast transient response, low dropout voltage, and tight load and line regulation.
The device is supplied in standard 3‑pin SOT‑89 and TO‑92 packages, with detailed pin assignments and ordering codes. The datasheet includes electrical characteristics, typical performance curves, application example circuits, and reliability test procedures.
