The MAX15029/MAX15030 low-dropout linear regulators operate from input voltages as low as 1.425V and deliver up to 500mA of continuous output current with a typical dropout voltage of only 40mV. The output voltage is adjustable from 0.5V to VIN and is ±2% accurate over load and line variations, from -40°C to +125°C. The MAX15030 features a BIAS input of 3V to 5.5V from an always-on power supply. The BIAS input current is reduced down to less than 2µA during the shutdown.
These regulators use small, 1µF ceramic input capacitors and 2.2µF ceramic output capacitors to deliver 500mA output current. High bandwidth provides excellent transient response and limits the output voltage deviation to 10mV for a 100mA to 500mA load step, with only a 2.2µF ceramic output capacitor, and the voltage deviations can be reduced further by increasing the output capacitor.
These devices offer a logic-controlled shutdown input to reduce input current (IIN) consumption down to less than 5.5µA in standby mode. Other features include a soft-start to reduce inrush current, short-circuit protection, and thermal-overload protection.
The MAX15030 features a BIAS input allowing a secondary supply to keep the LDO's internal circuitry alive if the voltage on IN goes to 0. Both devices are fully specified from -40°C to +125°C and are available in a 10-pin thermally enhanced TDFN package (3mm x 3mm) that includes an exposed pad for optimal power dissipation. For a 1A version of these LDOs, refer to the MAX15027/MAX15028 data sheet.
