Description
TLE4263-2ES is a monolithic integrated very low dropout voltage regulator in a SMD package PG-DSO-8 exposed pad, especially designed for automotive applications. An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 180 mA. The IC is short-circ uit proof by the implemented current limitation and has an integrated overtemperature shutdown. It additionally provides features like power-on and undervoltage reset with adjustable reset threshold, a watchdog circuit for monitoring a connected microcontroller and an inhibit input for enabling or disabling the component. The reset output RO is set to “low” in case the output voltage falls below the reset switching threshold VQ,rt. This threshold can be decreased down to 3.5 V by an external resistor divider. The power-on reset delay time can be programmed by the external delay capacitor CD. The watchdog circuit provides a monitoring function fo r microcontrollers: At missing pulses on the watchdog’s input W the reset output RO is set to “low”. The trigger time for the watchdog pulses can be set by the external capacitor CD. The IC can be switched off by the inhibit input, reducing the current consumption to typically 0 µA.
Data Sheet 3 Rev. 1.0, 2008-04-21 TLE4263-2ES Overview Dimensioning Information on External Components The input capacitor CI is recommended for compensation of line influences. The output capacitor CQ is necessary for the stability of the control loop . Stability is guara nteed at values ≥ 22 µF and an ESR of ≤ 3 Ω within the operating temperature range. For small tolerances of the reset delay the capacitance’s spread of the delay capacitor CD and its temperature coefficient should be taken into consideration. Circuit Description 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 component also has a number of internal circuits for protection against:
- Overload
- Overtemperature
- Reverse polarity In case the externally scaled down output voltage at the reset adjust input falls below 1.35 V, the external reset delay capacitor CD is discharged by the reset generator. When the voltage of the capacitor reaches the lower threshold VDRL, a reset signal occurs at the reset output and is held until the upper threshold VDU is exceeded. If the reset threshold input is connected to GND, reset is triggered at an output voltage of typically 4.65 V.
