Product details

Overview

TLE7270GNTMA1 from Infineon is a monolithic 5-V ±2% low-dropout linear voltage regulator with integrated reset generator, 300 mA output current capability, ultra-low quiescent current (20 µA typ.), and automotive-grade overtemperature/short-circuit protection. It operates from 5.5 V to 42 V input and delivers stable 5 V supply for microcontrollers in battery-permanent automotive systems.

For engineers reviewing the TLE7270GNTMA1 datasheet, TLE7270GNTMA1 pinout, TLE7270GNTMA1 application, or TLE7270GNTMA1 equivalent, key selection criteria include reset delay timing selectability (10 ms / 80 ms), ceramic capacitor stability down to 470 nF, reverse-current sink protection at Q pin, and thermal resistance of 55 K/W in TO263-5 package.

Technical Context

The TLE7270GNTMA1 implements a charge-pump-based LDO architecture enabling ultra-low quiescent current while maintaining regulation across wide input (5.5–42 V) and load (0.1–300 mA) ranges. Its internal bandgap reference and reset generator provide precise 4.65 V reset threshold with 100 mV hysteresis.

Reset delay time is selected via DT pin: grounded for 10–22 ms, tied to Q for 80–176 ms. The open-collector RO output includes a 30 kΩ internal pull-up and supports external ≥10 kΩ pull-up to Q, enabling flexible microcontroller reset sequencing in harsh automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	5.0 V ±2% - ensures reliable µC core logic supply within JEDEC Level A tolerance
Quiescent Current	20 µA typ. - enables always-on battery-connected operation without excessive drain
Max Output Current	300 mA - sufficient for MCU + peripheral ICs in body control modules
Drop Voltage	200 mV @ 200 mA - allows regulation down to VI = 5.2 V, critical for cold-crank scenarios
Reset Threshold	4.65 V typ. with 100 mV hysteresis - prevents spurious resets during transient dips
Output Capacitor	≥470 nF ceramic - enables compact, high-reliability layout without tantalum or electrolytic
Thermal Resistance	55 K/W (TO263-5) - supports 300 mA continuous operation at Tj ≤ 150 °C on standard FR4 PCB

Pinout & Package

Package: P-TO263-5-1 (D2-PAK), surface-mount, exposed heatsink tab (Pin 3 internally connected to GND and heatsink).

Pin/Terminal	Circuit Role	Design Meaning
1 (I)	Input	Primary VIN connection; requires local 100 nF ceramic decoupling directly at pin
2 (RO)	Reset Output	Open-collector reset signal with 30 kΩ internal pull-up; sinks current when VQ < 4.65 V
3 (GND)	Ground / Heatsink	Electrical ground reference and thermal path; must be soldered to large copper pour
4 (DT)	Delay Time Select	Logic-selectable reset delay: GND = 10–22 ms, Q = 80–176 ms
5 (Q)	Regulated Output	5 V regulated output; includes internal sink circuit limiting reverse voltage to ≤5.5 V

Key Features

Feature	Design Value
Two-step programmable reset delay	Selectable 10 ms or 80 ms delay via DT pin, enabling robust power-on sequencing for diverse µC families
Reverse-current sink protection	Internal circuit clamps Q pin voltage to ≤5.5 V during reverse current, preventing damage to downstream logic
Ceramic capacitor stability	Stable with ≥470 nF ceramic output cap (ESR < 3 Ω), eliminating need for bulkier, less reliable electrolytics
Automotive-grade protection	Integrated short-circuit, overtemperature, and overload protection meets AEC-Q100 stress requirements
Ultra-low-noise trade-off awareness	Charge-pump operation causes mV-range output noise - documented as inherent to 20 µA IQ design, not a defect

Equivalent & Alternatives

The following parts are listed as comparable options for similar 5 V automotive LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV70750PDBVR	Lower IQ (250 nA), lower current (300 mA), no integrated reset, SOT-23-5 package	Lacks reset functionality and automotive qualification; suitable only for non-safety-critical consumer-grade always-on rails	Choose only if reset is handled externally and AEC-Q100 is not required
TLE4270-2G	Same family, 5 V ±2%, 300 mA, but fixed 100 ms reset delay and TO252-5 package (R_thj-a = 80 K/W)	Higher thermal resistance limits continuous current in high-ambient environments vs. TO263-5	Prefer TLE7270GNTMA1 when board space allows TO263 and thermal performance is critical

Compared with TLV70750PDBVR, TLE7270GNTMA1 provides automotive-qualified reset and superior thermal performance; compared with TLE4270-2G, it offers selectable reset timing and lower thermal resistance-critical for sustained 300 mA operation in under-hood applications.

FAQ

What is the maximum allowable input voltage for continuous operation?

The TLE7270GNTMA1 supports continuous operation up to 42 V input, verified per its absolute maximum rating (VI = 45 V) and operating range (VI = 5.5–42 V). This withstands automotive load-dump transients per ISO 7637-2 Pulse 5a, provided external TVS protection is used for >42 V spikes.

Can the reset output (RO) drive a microcontroller reset pin directly?

Yes - RO is an open-collector output with a 30 kΩ internal pull-up resistor. It can directly assert active-low reset on most automotive microcontrollers. An external ≥10 kΩ pull-up to Q is optional for stronger drive or noise immunity, but not required for basic functionality.

Why does the datasheet specify mV-range output noise despite being an LDO?

This noise arises from the charge-pump circuit used to achieve 20 µA quiescent current. It is an inherent trade-off documented in the datasheet-not a defect-and is acceptable for digital logic supply. For analog-sensitive applications, Infineon recommends the TLE42XY series instead.

Is the TLE7270GNTMA1 pin-compatible with other TLE7270 variants?

Yes - all TLE7270 variants (including D-PAK and D2-PAK packages) share identical pinout (I, RO, GND, DT, Q) and electrical behavior. The GNTMA1 (TO263-5) differs only in thermal performance (R_thj-a = 55 K/W vs. 80 K/W for TO252-5), making it drop-in compatible where board layout permits the larger footprint.
