The MAX8869 is a 1A low dropout linear regulator that operates from a +2.7V to +5.5V input and delivers a guaranteed 1A load current with a low 200mV dropout.
The MAX8869 linear regulator operates from a 2.7 V to 5.5 V input and delivers a guaranteed 1 A load current with a low 200 mV dropout. It uses MicroCap™ technology and requires only a 1 pF output capacitor for stability, making it suitable for telecom, networking, and battery‑operated equipment.
Key features include soft‑start, low‑power shutdown (0.1 µA), short‑circuit protection, thermal overload protection, and a 16‑pin TSSOP‑EP package that is 30 % smaller than a SOT223. The device offers preset output voltages (+5 V, +3.3 V, +2.5 V, +1.8 V, +1.0 V) and an adjustable range from +0.8 V to +5 V via an external resistor divider.
