MAX8516, MAX8517, MAX8518 1.425V To 3.6V Input, 1A, 0.2V Dropout LDO Regulators
The MAX8516 MAX8517 MAX8518 low-dropout linear Regulators operate from input voltages as low as 1.425V and are able to deliver up to 1A of continuous output current with a maximum dropout voltage of only 200mV. The output voltage CAN be set from 0.5V to (VIN - 0.2V) and is 1.4% accurate over load and line variations, from 0C to +85C.
These Regulators use small, 1F ceramic input capacitors and 4.7F ceramic output capacitors to deliver 1A output current. High bandwidth provides excellent transient response and limits the output voltage deviation to 45mV for a 20mA to 1A load step, with only a 4.7F ceramic output capacitor, and the voltage deviations CAN be reduced further by increasing the output capacitor.
Designed with an internal P-Channel MOSFET pass Transistor the MAX8516 MAX8517 MAX8518 feature low 340A (typ) supply current during dropout conditions. Soft-start reduces inrush current. Other features include a logic-controlled shutdown mode, short-circuit protection, and thermal-overload protection.
The MAX8517 features a power-OK (POK) output that transitions high when the Regulator output is within 10% of its nominal output voltage. The MAX8518 features a 150ms power-on reset output.
The parts are packaged in a 10-pin MAX package that includes an exposed pad for optimal power dispation.
