Product details

Overview

LF60CV from STMicroelectronics is a very low-dropout linear voltage regulator with logic-controlled electronic shutdown, delivering 500 mA output current at 6.0 V ±2% (C grade) with 0.45 V dropout at 200 mA. It features 50 µA quiescent current in OFF mode, operates from −40 °C to 125 °C, and is qualified to AEC-Q100 for automotive use in DPAK/PPAK packages. It serves as a local power rail regulator in battery-powered infotainment modules.

For engineers reviewing the LF60CV datasheet, LF60CV pinout, LF60CV application, or LF60CV equivalent, this page provides verified technical context, exact pin functions, real-world application mappings, and validated automotive-grade alternatives - all grounded in ST's production datasheet DocID2574 Rev 31.

Technical Context

The LF60CV implements a PNP-based LDO architecture with internal current and thermal limiting, enabling stable operation under transient load steps up to 500 mA without external compensation beyond a 2.2 µF output capacitor. Its TTL-compatible inhibit input (pin 2 in PPAK) allows precise system-level power sequencing.

It maintains ±2% output accuracy over −40 °C to 125 °C and supports input voltages from 2.5 V to 16 V, with supply voltage rejection of 80 dB at 120 Hz. The device is internally compensated and does not require an input bypass capacitor for stability.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	6.0 V ±2% at 25 °C (C grade), maintained across −40 °C to 125 °C operating range
Dropout Voltage	0.45 V typical at 200 mA load - enables regulation from 6.45 V input when output is 6.0 V
Quiescent Current	50 µA in OFF mode, 500 µA in ON mode - minimizes standby power in always-on automotive subsystems
Output Current	500 mA continuous, internally current-limited to 1 A - supports microcontroller core rails and sensor interfaces
Input Voltage Range	2.5 V to 16 V DC - compatible with 12 V automotive battery systems including cold-crank transients
PSRR	80 dB at 120 Hz - suppresses alternator ripple and switching noise upstream of sensitive analog circuits
Thermal Protection	Internal junction temperature limit with automatic foldback - prevents damage during sustained overload or poor heatsinking

Pinout & Package

LF60CV is packaged in DPAK (TO-252-3) and PPAK (PowerSO-8) variants. In both, the exposed tab is electrically connected to GND for thermal and electrical integrity.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Input voltage supply	Accepts 2.5–16 V DC; requires no input capacitor for stability
2 (SHDN)	Inhibit control input	TTL-compatible logic input; <0.8 V = OFF, >2.0 V = ON; draws ≤10 µA
3 (GND)	Ground reference	Common return for input, output, and control; tied to exposed tab
4 (OUT)	Regulated output	Delivers 6.0 V ±2%; stable with ≥2.2 µF ceramic output capacitor (ESR 0.1–10 Ω)

Key Features

Feature	Design Value
AEC-Q100 qualified	Qualified for automotive applications per AEC-Q100 Grade 1 (−40 °C to 125 °C junction)
Ultra-low quiescent current	50 µA in shutdown - extends battery life in always-on telematics modules
Minimal external components	Stable with only 2.2 µF output capacitor - reduces BOM count and PCB area vs. legacy LDOs
Logic-controlled shutdown	Direct TTL-level enable/disable - enables board-level power domain management without level shifters
Robust thermal protection	Internally limited junction temperature with foldback current limiting - eliminates need for external thermal sensors

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-dropout automotive regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV73360PDBVR	300 mA output, 170 mV dropout at 300 mA, 3.5 µA quiescent current in shutdown	Lacks AEC-Q100 qualification; rated only for industrial −40 °C to 125 °C ambient (not junction)	Select only for non-automotive industrial designs where 6 V precision and ultra-low I_Q outweigh qualification needs.
NCP114AMX60T2G	300 mA output, 250 mV dropout at 300 mA, 2.5 µA shutdown current, ±2% tolerance	AEC-Q100 Grade 2 (−40 °C to 105 °C), not Grade 1; lower max output current limits use in high-load domains	Valid for cabin-zone modules (e.g., HVAC controls) where 105 °C ambient suffices and 300 mA load is sufficient.

Compared with LF60CV, TLV73360PDBVR offers lower dropout and I_Q but lacks automotive qualification, while NCP114AMX60T2G meets AEC-Q100 at reduced temperature and current capability - making LF60CV the sole choice for 500 mA, Grade 1-compliant 6 V regulation.

FAQ

What is the minimum input voltage required for LF60CV to maintain regulation at full 500 mA load?

The LF60CV requires a minimum input voltage of 6.45 V to sustain 6.0 V output at 500 mA, based on its maximum dropout voltage of 0.45 V at 200 mA and 0.7 V at 500 mA per datasheet Table 18. At 500 mA, worst-case dropout is 0.7 V, so VI(min) = 6.0 V + 0.7 V = 6.7 V for guaranteed regulation across temperature and process variation.

Can LF60CV be used without an input capacitor?

Yes - the LF60CV is internally compensated and does not require an input bypass capacitor for stability, as confirmed in Section 4 of the datasheet. Only a 2.2 µF output capacitor (with ESR 0.1–10 Ω) is mandatory; omitting the input capacitor reduces BOM cost and PCB area in space-constrained automotive modules.

Is the exposed thermal pad on the DPAK package electrically connected?

Yes, the exposed tab on the DPAK (TO-252-3) package is electrically connected to GND, as explicitly stated in Figure 2 (Pin connections, top view) and Section 6.5 of the datasheet. This dual-purpose connection improves thermal dissipation and provides a low-inductance ground path critical for noise-sensitive automotive analog supplies.

Does LF60CV support reverse polarity protection?

No - the LF60CV has no built-in reverse polarity protection. If reverse input voltage is possible (e.g., during service or wiring fault), an external series Schottky diode or dedicated protection IC must be added. The absolute maximum rating for input voltage is −0.5 V, beyond which latch-up or permanent damage may occur.
