The fixed output voltage makes the TLS202B1MBV50 suitable for supplying the majority of standard applications. The TLS202B1MBV50 is a monolithic integrated fixed linear voltage post regulator for load currents up to 150 mA. The IC regulates an input voltage VI up to 18 V to a fixed output voltage of 3.3 V with an accuracy of 3 %. The TLS202B1MBV50 is especially designed for applications requiring very low standby current, for example with a permanent connection to the preregulators such as DC-DC converters. The regulator is not designed to operate with a direct connection to the battery. The voltage regulator can be enabled and disabled via the Enable input. The device is available in a very small surface mounted PG_SCT595 package and 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 TLS202B1MBV50 can be also used in all other applications requiring a stabilized 3.3 V voltage. 1.1 TLS202B1MBV50 features * Output voltage: 3.3 V * Output voltage accuracy of 3 % * Output current up to 150 mA * Extended input voltage operating range of 2.7 V to 18 V * Enable functionality * Low dropout voltage: typ. 290 mV * Very low current consumption: typ. 50 A * Very low shutdown current: typ. 0.01 A * Very high PSRR: typically 63 dB at 10 kHz * Output current limitation * Short circuit protection * Overtemperature shutdown * Wide temperature range From -40C to 150C * Suitable for use as post regulator in automotive applications * Green product (RoHS compliant) * AEC qualified Application Note 3 Rev. 1.0 2017-10-26 TLS202B1MBV50 Demoboard Z8F60341179 Introduction 1.2 Block diagram I Q Current Limitation Driver EN Temperature Shutdown Internal Supply Bandgap Reference GND Figure 1 Block diagram of TLS202B1MBV50 Application Note 4 Rev. 1.0 2017-10-26 TLS202B1MBV50 Demoboard Z8F60341179 Demoboard 2 Demoboard The TLS202B1MBV50 demoboard is equiped by default with TLS202B1MBV50 and all necessary components.
