AP139-TWA 数据手册
AP139 300mA Low-Noise CMOS LDO Features - Very low dropout voltage - Low current consumption: Typ.45µA, Max. 60µA - Output voltage: 1.5V,1.8V,2.0V, 2.5V, 2.8V, 3.0V 3.3V, and 3.5V - Guaranteed 300mA output - Input range up to 7.0V - Thermal shutdown - Current limiting - Stability with low ESR capacitors - Low temperature coefficient - Pb-free package: SOT23-5L,TSOT23-5L General Descriptions The AP139 is a positive voltage linear regulator utilizing CMOS technology. The features that include low quiescent current (45µA typ.), low dropout voltage, and high output voltage accuracy, make it ideal for battery applications. EN input connected to CMOS has low bias current. The space-saving SOT23-5L and TSOT23-5L package is attractive for “Pocket” and “Hand Held” applications. This rugged device has both thermal shutdown, and current limit protections to prevent device failure under the “Worst” operating conditions. In a low noise, regulated supply application, a 10nF capacitor is necessary to be placed in between Bypass and Ground. The AP139 is stable with a low ESR output capacitor of 1.0µF or greater. Applications - Battery-powered devices - Personal communication devices - Home electric/electronic appliances - PC peripherals Pin Assignments (Top View) Pin Descriptions 4 VOUT 5 BYP AP139 Pin Name VIN GND EN BYP VOUT Pin No. 1 2 3 4 5 Function Power Supply Ground Enable Pin Bypass Signal Pin Output 1 2 3 VIN GND EN SOT23-5/TSOT23-5 Ordering Information AP139 Output voltage 15: 1.5V 18: 1.8V 20: 2.0V 25: 2.5V 28: 2.8V 30: 3.0V 33: 3.3V 35: 3.5V XX X X Package W : SOT23-5L TW:TSOT23-5L Packing Blank: Tube A: Taping This datasheet contains new product information.
