1A, Microcap, Low-Dropout, Linear Regulator
Compact, 1A, Low-Dropout Linear Regulator Requires Just 1µF Output Capacitor!
DescriptionThe MAX8869 low-dropout linear regulator operates from a +2.7V to +5.5V input and delivers a guaranteed 1A load current with a low 200mV dropout. The high-accuracy (±1%) output voltage is preset at +5V, +3.3V, +2.5V, +1.8V, or +1.0V or is adjustable from +0.8V to +5V with an external resistor-divider.
The MAX8869 uses Microcap® technology and requires only a small 1µF output capacitor for guaranteed stability. An internal PMOS pass transistor allows low 500µA supply current, making this regulator useful for networking and telecom hardware as well as battery-operated equipment. Other features include soft-start, low-power shutdown, short-circuit protection, and thermal shutdown protection.
The MAX8869 is available in a 1.5W, 16-pin TSSOP package, which is 30% smaller than a SOT223 and only 1.1mm high.
