DESCRIPTION/ORDERING INFORMATION
The TLE4275 is a monolithic integrated low-dropout voltage regulator offered in a 5-pin TO package. An input
voltage up to 45 V is regulated to V
= 5 V (typ). The device can drive loads up to 450 mA and is short-circuit
proof. At overtemperature, the TLE4275 is turned off by the incorporated temperature protection. A reset signal
is generated for an output voltage, V
OUT,rt
, of 4.65 V (typ). The reset delay time can be programmed by the
external delay capacitor.
The input capacitor, C
IN
, compensates for line fluctuation. Using a resistor of approximately 1
, in series with
C
IN
, dampens the oscillation of input inductivity and input capacitance. The output capacitor, C
OUT
, stabilizes the
regulation circuit. Stability is specified at C

, within the operating temperature range.
The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and
drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents
any oversaturation of the power element. The device also incorporates a number of internal circuits for
protection against:
Overload
Overtemperature
Reverse polarity
