Functional Description
The TLS202A1 is a monolithic integrated adjustable linear voltage post regulator for load currents up to 150 mA.
The IC regulates an input voltage VI in the range of 2.7 V ≤ VI ≤ 18 V to an adjustable output voltage of 1.2 V to
5.25 V with a precision of ±3 %. The TLS202A1 is especially designed for applications requiring very low standby
currents, e.g. with a permanent connection to preregulators like DCDC converters. The regulator is not designed
to operate with a direct connection to the battery. The device is available in a very small surface mounted PGSCT595 package. The device is designed for the harsh environment of automotive applications. Therefore it is
protected against overload, short circuit and overtemperature conditions by the implemented output current
limitation and the overtemperature shutdown circuit. The TLS202A1 can be also used in all other applications
requiring a stabilized voltage of 1.2 V to 5.25 V.
Choosing External Components
The input capacitor CI is recommended for compensating line influences. The output capacitor CQ is necessary
for the stability of the regulating circuit. Stability is guaranteed at values specified in “Functional Range” on
Page 6 within the whole operating temperature range.

Description Voltage Regulator
The output voltage VQ is controlled as follows: It is divided by the external resistor divider and this fraction is
distributed to the ADJ Pin. The Voltage at the ADJ is then compared to an internal reference and drives the pass
transistor accordingly.
By connecting the ADJ pin directly to the output Q the device will regulate to its reference voltage. In this case a
minimum load resistance of less than 1 MΩ needs to be ensured for stability reasons.
The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the circuit
design. To ensure stable operation, the requirements for output capacitance and equivalent series resistance
ESR, given in “Functional Range” on Page 6, have to be maintained. For details see also the typical stability
graph of ESR versus load current on Page 12. As the output capacitor also has to buffer load steps it should be
sized according to the needs of the application.
An input capacitor CI of at least 220 nF is recommended to compensate line influences. Connect the capacitors
close to the terminals of the component.
In case the load current is above the specified limit, e.g. in case of a short circuit, the output current limitation limits
the current. The output voltage is therefore decreasing at the same time.
The overtemperature shutdown circuit prevents the IC from immediate destruction under fault conditions (e.g.
output continuously short-circuited) by switching off the power stage. After the chip has cooled down, the regulator
restarts. This leads to an oscillatory behavior of the output voltage until the fault is removed. However, junction
temperatures above 150 °C are outside the maximum ratings and therefore significantly reduce the IC’s lifetime.

The Current Consumption of the device is characterizing the current the device needs to operate. The Quiescent
Current is describing the Current Consumption in a very low load condition (e.g. the supplied microcontroller is in
sleep mode). The Current Consumption of the device can be determined by measuring the Current flowing out of
the GND Pin and defined as the delta between II and IQ.

Application Diagram
Note: This is a very simplified example of an application circuit. The function must be verified in the real application.
The resistor divider for a specific output voltage can be calculated according to Equation (1). The current IADJ,
which flows into the ADJ-Pin, can be neglected, if Equation (2) is observed. VADJ is typically 1.2 V.

An optional Capacitor can be placed to improve the PSRR of this adjustable regulator for low currents smaller than
100 uA. The capacitance depends strongly on the used resistance. According to Equation (3) the right value of
the capacitance can be determined.
