Product details
Overview
LF60ABDT-TR from STMicroelectronics is a very low-dropout linear voltage regulator with logic-controlled electronic shutdown, delivering 6.0 V ±1% output at up to 500 mA. It features 0.45 V dropout at 200 mA, 50 µA quiescent current in OFF mode, and operates across –40 °C to 125 °C for automotive power rail conditioning in engine control units.
For engineers reviewing the LF60ABDT-TR datasheet, LF60ABDT-TR pinout, LF60ABDT-TR application, or LF60ABDT-TR equivalent, this device is selected for battery-powered systems requiring stable 6 V supply with ultra-low standby current, high PSRR (80 dB typ.), and AEC-Q100 qualified operation in DPAK packages.
Technical Context
The LF60ABDT-TR implements a PNP pass transistor architecture enabling sub-0.5 V dropout while maintaining tight output regulation under load transients. Its integrated inhibit function accepts TTL-compatible logic-level control (VIL ≤ 0.8 V, VIH ≥ 2.0 V) on Pin 2, enabling system-level power gating.
Stability is achieved with only 2.2 µF output capacitance (ESR 0.1–10 Ω), eliminating need for large ceramic or tantalum bypass capacitors. Internal thermal and current limiting protect against fault conditions without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 6.0 V ±1% at 25 °C; ensures precise MCU core or sensor biasing without post-regulation trimming |
| Dropout Voltage | 0.45 V at 200 mA; enables regulation from 6.45 V input, critical for 7–12 V automotive battery rails |
| Quiescent Current | 50 µA in OFF mode; reduces standby power to <15 µW at 6 V, extending battery life in always-on modules |
| Output Current | 500 mA continuous; supports multi-rail local regulation for microcontrollers, CAN transceivers, and analog sensors |
| PSRR | 80 dB at 120 Hz; suppresses alternator ripple and switching noise before sensitive analog subsystems |
| Operating Temp | –40 °C to 125 °C junction; validated per AEC-Q100 Grade 1 for under-hood automotive deployment |
| Capacitor Requirement | 2.2 µF ceramic output capacitor; minimizes PCB area and cost vs. legacy LDOs needing ≥10 µF |
Pinout & Package
DPAK (TO-252-3) package with exposed thermal pad electrically connected to GND; thermally optimized for surface-mount automotive PCBs with moderate airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 7–16 V DC; internal overvoltage clamp activates above 40 V |
| 2 (INH) | Inhibit control input | TTL-compatible shutdown pin; pulls output to high-impedance when ≤0.8 V |
| 3 (GND) | Ground reference | Common return for IN, INH, and OUT; tied to exposed thermal pad |
| 4 (OUT) | Regulated output | Delivers 6.0 V ±1%; requires 2.2 µF ceramic capacitor to OUT–GND for stability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LDL112PU33R | Fixed 3.3 V output; 250 mA max; no inhibit pin; SOT-23-5 package | Not suitable for 6 V systems or remote shutdown; limited to low-current digital I/O rails | Select only if output voltage and current requirements align and shutdown control is unnecessary |
| TLV73360PDBVR | 6 V output; 300 mA; 25 µA quiescent current; no AEC-Q100 qualification; SOT-23-5 | Lacks automotive temperature range and qualification; unsuitable for under-hood use | Consider for non-automotive industrial or consumer applications where cost and size outweigh qualification needs |
Compared with LF60ABDT-TR, LDL112PU33R lacks voltage flexibility and shutdown capability, while TLV73360PDBVR trades AEC-Q100 compliance and 500 mA drive for lower quiescent current and smaller footprint-making LF60ABDT-TR the sole choice for qualified 6 V automotive LDO applications demanding robustness and system-level power control.

FAQ
What is the minimum input voltage required for regulation at full 500 mA load?
The LF60ABDT-TR maintains regulation down to an input voltage of 6.45 V at 500 mA load, based on its maximum dropout voltage of 0.45 V. Below this threshold, output voltage collapses linearly with input; operation below 7 V is supported only under light loads per the datasheet's dropout curves.
Can the INH pin be left floating, or must it be actively driven?
The INH pin must never be left floating: it has no internal pull-up or pull-down. An unconnected INH pin may float into the undefined logic region (0.8–2.0 V), causing unpredictable ON/OFF behavior. Tie to GND for permanent enable or to a controlled GPIO for active shutdown.
Is the exposed thermal pad on the DPAK package required to be soldered to PCB copper?
Yes-the exposed thermal pad is electrically connected to GND and serves as the primary heat path. ST recommends soldering it to a minimum 100 mm² GND copper pour with ≥4 thermal vias (0.3 mm diameter) to achieve specified RthJA = 100 °C/W and prevent thermal shutdown above 125 °C junction temperature.
Does the 2.2 µF output capacitor requirement apply to all load conditions and temperatures?
Yes-the 2.2 µF ceramic capacitor (X5R/X7R, ESR 0.1–10 Ω) ensures stability across –40 °C to 125 °C and 0–500 mA load range per ST's characterization. Larger values do not improve stability but may degrade transient response; smaller values risk oscillation, especially at low temperatures or high ESR.
