AP130-18WL-7

AP130 300mA LOW DROPOUT (LDO) LINEAR REGULATOR Features Description • Input Voltage Range: 2.7V to 5.5V • Dropout Voltage 400mV at 300mA Output Current • Guaranteed 300mA Output Current • Internal RON = 1.5Ω PMOS Draws No Base Current • Low Quiescent Current 50µA The AP130 is a 300mA, fixed output voltage, low dropout linear regulator. The device includes pass element, error amplifier, band-gap, current-limit and thermal shutdown circuitry. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. The typical quiescent current is approximately 50µA from zero to maximum load. Due to internal flexible design, results in extensively fixed output voltage versions and make it convenient to use for applications. Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage. • Output Voltage: 1.5V/1.8V/2.0V/2.5V/2.8V/3.0V/ • 3.3V/3.5; Accuracy 2% • Fast Transient Response • Good Load Regulation • Current Limit and Thermal Shutdown Protection • Short Circuit Current Fold-Back • Lead Free Packages: SC59, SC59R, SOT89-3L, and SOT89R-3L • SC59, SC59R, SOT23, SOT89-3L, and SOT89R-3L: Available in “Green” Molding Compound (No Br, Sb) (Note 9) • Lead Free Finish/ RoHS Compliant (Note 1) Notes: 1.

Dropout voltage is defined as the input to output differential voltage. Dropout is measured at constant junction temperature by using pulsed on time, and the criterion is VOUT inside target value ±2%. This test is skipped at the condition of VIN
