AS1363

AS1363 1A Low Dropout Linear Voltage Regulator 1 General Description The AS1363 is a low-dropout linear regulator that operates from a +2.0V to +5.5V supply and delivers a guaranteed 500mA load current with low 150mV dropout. The device is available in two versions (see Table 1). One version has a high-accuracy output with a preset voltage (1.2V, 1.5V, 1.8V, 3.0V, 3.3V, or 4.5V). This voltage is internally trimmed and also offers a Bypass pin. With a capacitor connected to this Bypass pin, the PSRR and the Noise performance is improved. At the other version the output voltage is user-adjustable (1.2V to 5.3V) and offers an SET pin for setting the output voltage. Table 1.

Other features are included such as an active-low open-drain reset output that indicates when the o...
