Product details
Overview
LF60CDT-TR from STMicroelectronics is a 6.0 V, ±2% automotive-grade low-dropout linear regulator in PPAK-5 package with 0.45 V dropout at 500 mA, 50 µA quiescent current in OFF mode, and logic-controlled shutdown (TTL-compatible enable pin). It serves as a local power supply for infotainment microcontrollers, ADAS sensor modules, and body control units requiring stable 6 V bias under cold-crank conditions.
For engineers reviewing the LF60CDT-TR datasheet, LF60CDT-TR pinout, LF60CDT-TR application, or LF60CDT-TR equivalent, this page delivers verified electrical specs, automotive qualification status (AEC-Q100 Grade 1), thermal performance (RthJA = 100 °C/W), and real-world design implications for battery-powered vehicle subsystems.
Technical Context
The LF60CDT-TR implements a PMOS pass transistor architecture enabling ultra-low dropout voltage (0.45 V at 500 mA) and high PSRR (80 dB typ. at 120 Hz). Its internal current and thermal limiting protect against overload and short-circuit faults without external components.
It features a dedicated TTL-compatible enable input (pin 2) that places the regulator in ultra-low-power OFF state (50 µA IQ) while maintaining output isolation. The device operates across –40 °C to +125 °C junction temperature and requires only a 2.2 µF ceramic output capacitor for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 6.0 V ±2% at 25 °C; ensures reliable MCU core/buffer rail within automotive supply tolerance bands |
| Dropout voltage | 0.45 V at 500 mA; enables operation down to 6.45 V input during 7 V cold-crank events |
| Quiescent current | 50 µA in OFF mode; reduces standby power in always-on vehicle networks |
| Output current | 500 mA continuous; supports multi-rail local regulation for SoC peripherals |
| PSRR | 80 dB at 120 Hz; suppresses alternator ripple and switching noise from upstream DC/DC stages |
| Operating temp | –40 °C to +125 °C; qualified per AEC-Q100 Grade 1 for engine bay and cabin applications |
| Stability cap | 2.2 µF ceramic (ESR 0.1–10 Ω); eliminates need for bulky tantalum or electrolytic capacitors |
Pinout & Package
LF60CDT-TR uses the PPAK-5 surface-mount package (4.5 × 3.5 × 1.0 mm), with exposed thermal pad electrically connected to GND for enhanced heat dissipation. The package is qualified for automotive reflow profiles and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – IN | Input voltage supply | Accepts 7–16 V DC; withstands transient spikes up to 40 V (clamped by internal protection) |
| 2 – EN | Enable control input | TTL-compatible logic input; <0.8 V disables regulator (50 µA IQ), >2 V enables (500 µA IQ) |
| 3 – GND | Ground reference | Common return path for input, output, and enable; tied to exposed thermal pad |
| 4 – OUT | Regulated output | Delivers 6.0 V ±2% at up to 500 mA; requires ≥2.2 µF ceramic capacitor on PCB |
| 5 – TAB | Thermal pad / GND | Electrically connected to GND; must be soldered to large copper pour for RthJA ≤ 100 °C/W |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified with PAT/SYL/SBL statistical testing; valid for under-hood deployment |
| Logic-controlled shutdown | Dedicated EN pin enables system-level power gating of downstream circuits without external FETs |
| Low-noise regulation | 50 µVRMS output noise (10 Hz–100 kHz); avoids interference with analog sensors and RF receivers |
| Robust thermal management | Internally limited junction temperature + RthJC = 8 °C/W enables >1 W dissipation in PPAK-5 with minimal PCB copper |
| Wide input range | Operates from 7 V to 16 V input; supports 12 V vehicle systems including load-dump and jump-start transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LDL112PU33R | 3.3 V output, 200 mA max, 0.35 V dropout, SOT-323-5 package | Limited to lower-current, lower-voltage rails; no automotive qualification | Select only for non-automotive 3.3 V point-of-load use where space is critical |
| TLD1120-16ES | 6.0 V output, 1.2 A max, integrated reverse-polarity protection, TO-252-5 | Higher current, larger footprint, includes protection features not present in LF60CDT-TR | Choose when reverse-battery immunity and >500 mA load are required; adds cost and size |
Compared with LDL112PU33R and TLD1120-16ES, LF60CDT-TR uniquely balances 6 V output, 500 mA capability, AEC-Q100 compliance, and PPAK-5 compactness-making it optimal for space-constrained, safety-critical 6 V domains where external protection is already implemented.

FAQ
What is the maximum input voltage rating for LF60CDT-TR?
The absolute maximum DC input voltage is 40 V, but the device enters shutdown above 18 V. For normal regulation, input must remain between 7 V and 16 V. This range accommodates automotive battery transients including ISO 7637-2 pulse 5a (load dump) when used with appropriate front-end clamping.
Does LF60CDT-TR require an input bypass capacitor?
Yes - a minimum 0.1 µF ceramic capacitor is required between IN and GND, placed as close as possible to pins 1 and 3. This stabilizes the input impedance and prevents oscillation during fast load transients, especially when long input traces are present.
How does the EN pin behave during power-up?
The EN pin has an internal pull-down resistor (~1 MΩ), ensuring the device remains disabled until a valid high logic level (>2 V) is applied. This prevents uncontrolled output activation during system reset or brown-out conditions, supporting safe power sequencing.
Is the thermal pad of LF60CDT-TR electrically isolated?
No - the exposed thermal pad (pin 5) is internally connected to GND. It must be soldered to a PCB GND plane with ≥4 thermal vias (0.3 mm diameter) to achieve the specified RthJA of 100 °C/W and prevent thermal shutdown under 500 mA load at 85 °C ambient.
