| AP139 300mA Low-Noise CMOS LDO Features - Very low dropout voltage - Low current consumption: Typ.45A, Max. 60A - 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 (45A 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 1.0F or greater.

The P-channel pass transistor receives data from the error amplifier, over-current protection, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and thermal shutdown circuits become active when the junction temperature exceeds 130oC, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 110oC. The AP139 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. Enable The enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shut off, and all internal circuits are powered down. In this state, the quiescent current is less than 2A. This pin behaves much like an electronic switch. External Capacitor The AP139 is stable with a low ESR output capacitor to ground of 1.0F or greater. It can keep stable even with higher ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 0.1F to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A "quiet" ground termination is desirable.
