TABLE 3-1: PIN FUNCTION TABLE 3.1 Ground Terminal (GND) Regulator ground. Tie GND to the negative side of the output and the negative side of the input capacitor. Only the LDO bias current (2 µA, typ.) flows out of this pin, there is no high current. The LDO output regulation is referenced to this pin. Minimize voltage drops between this pin and the negative side of the load. 3.2 Regulated Voltage Output (VOUT) Connect VOUT to the positive side of the load and the positive terminal of the output capacitor. The positive side of the output capacitor should be physically located as close as possible to the LDO VOUT pin. The current flowing out of this pin is equal to the DC load current. 3.3 Unregulated Supply Input (VIN) Connect the input supply voltage and the positive side of the input capacitor to VIN. Like all low-dropout linear regulators, low source impedance is necessary for the stable operation of the LDO. The amount of capacitance required to ensure low source impedance will depend on the proximity of the input source capacitors or battery type. The input capacitor should be physically located as close as possible to the VIN pin. For most applications, 1 µF of capacitance will ensure stable operation of the LDO circuit. For applications that have load currents below 100 mA, the input capacitance requirement can be lowered. The type of capacitor used can be ceramic, tantalum or aluminum electrolytic. The low equivalent series resistance characteristics of the ceramic will yield better noise and PSRR performance at high frequency. The current flow into this pin is equal to the DC load current, plus the LDO bias current (2 µA, typical).
