PRODUCT DESCRIPTION
The SPX1202 is a low power positive-voltage regulator designed to meet 600mA output current. This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The SPX1202 features very low quiescent current and very low dropout voltage of 1.2V at a full load and lower as output current decreases. This product is available as an adjustable or fixed 3V, 3.3V, and 5V output voltages.
The SPX1202 is offered in a 3-pin surface mount package SOT-223, TO-252, TO-220 & TO-263. The output capacitor of 10 F or larger is needed for output stability of SPX1202 as required by most of the other regulator circuits.

Note 1: Output temperature coefficient is defined as the worst case voltage change divided by the total temperature range
Note 2: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential at very low values of programmed output voltage, the minimum input supply voltage of 2V ( 2.3V over temperature) must be taken into account.
Note 3: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied. excluding loads or line regulation effect
