Functional Description

The TLS202B1 is a monolithic integrated fixed linear voltage post regulator for load currents up to 150 mA. The

IC regulates an input voltage V_Iup to 18 V to a fixed output voltage of 1.2 V to 5.25 V with a precision of ±3 %.

The TLS202B1 is especially designed for applications requiring very low standby currents, e.g. with a permanent

connection to the preregulators like DCDC converters. The regulator is not designed to operate with a direct

connection to the battery. The component can be enabled/disabled via the Enable input. The device is available

in a very small surface mounted PG-SCT595 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 TLS202B1 can be

also used in all other applications requiring a stabilized 1.2 V to 5.25 V voltage.

Choosing External Components

The input capacitor C_Iis recommended for compensating line influences. The output capacitor C_Qis 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.

Voltage Regulator

5.1

Description Voltage Regulator

The output voltage V_Qis controlled as follows: It is divided by the resistor divider. This fraction is then compared

to an internal reference and drives the pass transistor accordingly.

The control loop stability depends on the output capacitor C_Q, 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 10. As the output capacitor also has to buffer load steps it should be

sized according to the needs of the application.

An input capacitor C_Iis 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.

Current Consumption

6.1

Description Current Consumption

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 TLS202B1 has an Enable functionality to shutdown the device, in case it is not needed. During

shutdown the device has a very low Current Consumption. 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 I_Iand (I_Q+I_EN).

Application Diagram

Note:This is a very simplified example of an application circuit. The function must be verified in the real application.

A typical application circuit of the TLS202B1 is shown in Figure 5. It shows a generic configuration of the voltage

regulator, with the recommendable minimum number of components one should use. Theoretically, if there is no

risk of high frequency noise at all, even the small input filter capacitor can be omitted. For a normal operation mode

of the device only an output capacitor and a small ceramic input capacitor are needed. Depending on the

application’s environment, additional components like an input buffer capacitor or a reverse polarity protection

diode can be considered as well.

Input Filter Capacitor C_I

A small ceramic capacitor (e.g. 220nF in Figure 5) at the device input helps filtering high frequency noise. To

reach the best filter effect, this capacitor should be placed as close as possible to the input pin. The input filter

capacitor does not have an influence on the stability of the regulation loop of the device, but in case of fast load

changes an input capacitor can buffer the input voltage. Otherwise the parasitic inductance of the input line length

can drop the input voltage at the IC terminals and influence the output voltage.

Output Capacitor C_Q

The output capacitor is the external component that is required in any case as it is a part of the device’s regulation

loop. To maintain stability of this loop, the TLS202B1 requires at least an output capacitor respecting the values

given in “Functional Range” on Page 6. The given parameters ensure a stable regulation loop in general, in case

of fast load changes in the application the output capacitance may have to be increased according to the

requirements for load responses.
