PG-SOT223-4
Functional Description
TLE42364G is a low dropout voltage regulator for 5 V supply in a PG-SOT223-4 SMD package. The IC regulates
an input voltage VI in the range of 5.5 V < VI < 45 V to VQ,nom = 5 V. The maximum output current is more than 100
mA. The IC can be switched off via the enable input, which causes the current consumption to drop below 10 µA.
The IC is protected against shortcircuit and overheat by the incorporated output current limitation and the
overtemperature shutdown.
Choosing External Components
The input capacitor CI is necessary for compensating line influences. The output capacitor CQ is necessary for the
stability of the regulating circuit. Stability is guaranteed at values CQ 10 µF and an ESR 10 within the whole
operating temperature range.
Circuit Description
The device includes a precise reference voltage, which is very accurate due to resistor adjustment. A control amplifier
compares the divided output voltage to this reference voltage and drives the base of the PNP series transistor through a buffer.
Saturation control as a function of the load current prevents any oversaturation of the power element.
