Product details
Overview
TLS820D0ELV33XUMA1 from Infineon Technologies is a fixed-output 3.3 V, 200 mA automotive-grade low dropout linear voltage regulator in PG-SSOP-14 package, featuring ±2 % output voltage accuracy, 40 µA quiescent current, 80 mV typical dropout at 100 mA, and integrated enable, reset, and overtemperature protection. It powers microcontroller core supplies and sensor interfaces in engine control units under cranking conditions (down to 3.0 V input).
For engineers reviewing the TLS820D0ELV33XUMA1 datasheet, TLS820D0ELV33XUMA1 pinout, TLS820D0ELV33XUMA1 application, or TLS820D0ELV33XUMA1 equivalent, key selection criteria include guaranteed 3.3 V output stability with 1 µF ceramic capacitor, programmable reset delay (8.5 ms / 16.5 ms), adjustable reset threshold down to 2.50 V, and AEC-Q100 qualification for permanent battery-connected systems.
Technical Context
The TLS820D0ELV33XUMA1 implements a high-stability regulation loop optimized for low-ESR ceramic capacitors, enabling stable operation with only 1 µF output capacitance. Its internal bandgap reference and current-limiting circuitry support precise 3.3 V output across -40 °C to +150 °C junction temperature.
Enable control uses an integrated pull-down resistor; reset functionality includes undervoltage detection, power-on delay timing via DT pin, and threshold adjustment via RADJ pin. Protection features include thermal shutdown and short-circuit current limiting-designed for fault recovery without latch-up.

FAQ
What is the minimum input voltage required for regulated 3.3 V output?
The TLS820D0ELV33XUMA1 maintains regulation down to 3.0 V input-enabling operation during engine cranking in 12 V automotive systems. Below this, output drops linearly per the extended operating range specification; full regulation resumes once input exceeds 3.3 V + dropout (≈3.38 V).
Can the reset function be disabled entirely?
Yes. The reset function is disabled by leaving the RO pin unconnected and tying both RADJ and DT pins to GND. In this configuration, the internal reset circuit remains inactive, and RO stays high-impedance. No external pull-up is required unless reset signaling is needed.
Is an input capacitor mandatory?
A 100 nF ceramic capacitor placed close to the I pin and GND is strongly recommended to suppress high-frequency line noise and improve transient response. While not strictly mandatory for basic regulation, omission may cause instability under fast load steps or noisy battery conditions per Infineon's application guidance.
Does the exposed thermal pad require PCB copper area?
Yes. The exposed pad must be soldered to a dedicated PCB thermal pad connected to GND. Infineon specifies ≥100 mm² of 2-oz copper with ≥4 thermal vias (0.3 mm diameter) to achieve rated 200 mA output at +125 °C ambient. Omitting this compromises thermal performance and current capability.
