The AM8800/8811 family of positive, linear regulators from AME, Inc. features low quiescent current and low dropout voltage, making them ideal for battery applications. The space-saving SOT-23, SOT-25, SOT-89, and TO-92 packages are attractive for pocket and handheld applications. These rugged devices have both thermal shutdown and current fold-back to prevent device failure under the worst operating conditions. The AM8800/8811 is stable with an output capacitance of 2.2µF or greater.
The AME8800/8811 family are positive linear regulators offering very low quiescent current (30 µA typ.) and low dropout voltage, making them suitable for battery‑powered and handheld applications. They include protection features such as thermal shutdown, over‑temperature shutdown, and current fold‑back to safeguard the device under adverse conditions.
Available in compact SOT‑23, SOT‑25, SOT‑89 and TO‑92 packages, the regulators are offered with a range of preset output voltages from 1.5 V to 4.0 V. The datasheet lists detailed ordering information, pin configurations, and the operating temperature range of –40 °C to +85 °C.
