ELECTRICAL CHARACTERISTICS

Over operating junction temperature range (T_J= –40°C to +125°C), V_IN= V_OUT(NOM)+ 1 V, I_OUT= 1 mA, and C_OUT= 1 µF,

unless otherwise noted. Typical values are at T_J= +25°C.

(1) Minimum V_IN= V_OUT+ V_DOor the value shown for Input voltage in this table, whichever is greater.

(2) See Figure 1. The TPS715xx family employs a leakage null control circuit. This circuit is active only if output current is less than pass

FET leakage current. The circuit is typically active when output load is less than 5 µA, V_INis greater than 18 V, and die temperature is

greater than +100°C.
