一,产品概述(General Description)

The JTMA8800A is a low dropout, positive linear regulator with very low quiescent current.
The JTMA8800A can supply 300mA output current with low dropout voltage at about 250mV.
The BP pin with a 10nF bypass capacitor can help reduce the output noise level. The shutdown
function can provide remote control for the external signal to decide the on/off state of JTMA8800A.
With a logic high level at SHDN pin, the device is in the on state, and vice versa. The JTMA8800A
regulator is able to operate with output capacitors as small as 1 µ F for stability. Other than the
current limit protection, JTMA8800A also offers the on chip thermal shutdown feature providing
protection against overload or any condition when the ambient temperature exceeds the
maximum junction temperature. The JTMA8800A offers high precision output voltage of
+2%. It is available in fixed output voltages including 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V,
3.1V, 3.3V, 3.6V, 4.5V and 5.0V. The JTMA8800A is housed in low-profile, space-saving
SOT-23-5L & TSOT-23-5L package.
