Product details
Overview
LT3060IDC-2.5#TRMPBF from Analog Devices is a micropower, low-noise, 100mA low-dropout linear regulator with fixed 2.5V output, 300mV dropout at 100mA, 40µA quiescent current, and 30µVRMS output noise (10Hz–100kHz). It operates from 1.6V to 45V input and delivers stable power in battery-powered instrumentation and automotive control modules.
For engineers reviewing the LT3060IDC-2.5#TRMPBF datasheet, LT3060IDC-2.5#TRMPBF pinout, LT3060IDC-2.5#TRMPBF application, or LT3060IDC-2.5#TRMPBF equivalent, key selection factors include guaranteed ±2% output tolerance over line/load/temperature, reverse-battery protection, shutdown current <1µA, and compatibility with low-ESR ceramic capacitors without added series resistance.
Technical Context
The LT3060IDC-2.5#TRMPBF uses a PNP pass transistor architecture enabling ultra-low quiescent current and high PSRR at low frequencies. Its internal reference is stabilized by an external REF/BYP capacitor, enabling programmable soft-start and noise reduction.
It integrates reverse-battery, reverse-output, and reverse-current protection - critical for automotive and industrial environments where supply polarity faults occur. Thermal shutdown and foldback current limiting ensure safe operation under overload or short-circuit conditions without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% over line, load, and –40°C to 125°C temperature range - ensures precision biasing for ADC references and sensor interfaces. |
| Max Output Current | 100mA continuous - sufficient for powering microcontrollers, RF transceivers, or analog front-ends in compact systems. |
| Dropout Voltage | 300mV at 100mA - enables regulation from 2.8V input, supporting single-cell LiFePO₄ or dual-cell alkaline supplies. |
| Quiescent Current | 40µA typical - extends battery life in always-on monitoring devices; drops to <1µA in shutdown mode. |
| Output Noise | 30µVRMS (10Hz–100kHz) - meets low-noise requirements for precision analog signal chains and high-resolution data acquisition. |
| Input Voltage Range | 1.6V to 45V - accommodates wide-input industrial rails, automotive cold-crank (up to 45V), and legacy 24V/48V systems. |
| Ripple Rejection | 58dB at 120Hz (VIN = 4V avg) - suppresses rectified AC ripple in offline power supplies feeding downstream analog circuitry. |
Pinout & Package
LT3060IDC-2.5#TRMPBF is housed in an 8-lead, 2mm × 2mm × 0.75mm plastic DFN package with exposed thermal pad (Pin 9, GND), optimized for high-power-density PCB layouts and thermal performance (θJA = 48–60°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 1.6V–45V; must be decoupled with ≥1µF ceramic capacitor near pin for stability. |
| SHDN | Shutdown control input | Active-low logic input; pulls output off when <0.3V; draws <1µA when asserted. |
| OUT | Regulated output | Delivers 2.5V @ up to 100mA; requires ≥2.2µF low-ESR ceramic capacitor for transient response. |
| ADJ | Adjustment reference node | Internally connected to 600mV bandgap; unused in fixed-output variants but tied internally for accuracy. |
| GND | Ground reference | Common return for IN, OUT, SHDN, REF/BYP; exposed pad (Pin 9) must be soldered to PCB ground plane. |
| REF/BYP | Noise filter & soft-start node | Connects to 10nF capacitor to reduce reference noise and control output ramp rate during startup. |
Key Features
| Feature | Design Value |
|---|---|
| Single-capacitor soft-start | 10nF on REF/BYP pin controls output rise time and reduces inrush current - eliminates need for external timing resistors. |
| Reverse-battery protection | Withstands –45V on IN pin with no damage or reverse current flow - essential for automotive jump-start scenarios. |
| Reverse-output protection | Blocks >5µA reverse current when OUT > IN or VIN = 0V - prevents backfeeding into upstream supplies. |
| Thermal + current foldback limit | Shuts down at 125°C junction temp; current limit decreases as VIN–VOUT increases - protects against sustained overload. |
| AEC-Q100 qualified | Rated for automotive applications (Grade I: –40°C to 125°C) - validated for reliability in engine control, ADAS, and infotainment systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSM1052-2.5 | Higher quiescent current (85µA), lower PSRR (45dB @ 120Hz), no reverse-battery protection. | Suitable for cost-sensitive industrial controls where fault protection is handled externally. | Choose if budget constraints outweigh need for automotive-grade protection and ultra-low IQ. |

FAQ
What is the maximum input voltage rating for the LT3060IDC-2.5#TRMPBF?
The LT3060IDC-2.5#TRMPBF has an absolute maximum input voltage of ±50V on the IN pin, with recommended operating input range from 1.6V to 45V. Exceeding 45V may trigger overvoltage protection or degrade long-term reliability, and operation above 50V risks permanent damage per Absolute Maximum Ratings.
Does the LT3060IDC-2.5#TRMPBF require an external capacitor on the REF/BYP pin?
Yes - the LT3060IDC-2.5#TRMPBF requires a 10nF capacitor between REF/BYP and GND to achieve its specified 30µVRMS output noise and controlled soft-start behavior. Omitting this capacitor increases output noise and removes startup slew-rate control, potentially causing inrush-related system instability.
Is the LT3060IDC-2.5#TRMPBF pin-compatible with other variants in the LT3060 family?
Yes - all LT3060 fixed-output variants (e.g., LT3060IDC-1.5#TRMPBF, LT3060IDC-3.3#TRMPBF) and the adjustable LT3060IDC#TRMPBF share identical 8-lead DFN pinouts and thermal pad layout. This allows drop-in replacement across output voltages without PCB redesign, provided input/output capacitor values remain appropriate for the new VOUT.
What protection features does the LT3060IDC-2.5#TRMPBF include?
The LT3060IDC-2.5#TRMPBF integrates reverse-battery protection (survives –45V on IN), reverse-output protection (blocks >5µA reverse current when VIN = 0V), reverse-current protection (prevents backfeed during shutdown), thermal shutdown, and foldback current limiting - eliminating need for external protection diodes or FETs in most designs.
Can the LT3060IDC-2.5#TRMPBF operate with ceramic output capacitors only?
Yes - the LT3060IDC-2.5#TRMPBF is explicitly optimized for low-ESR ceramic output capacitors (minimum 2.2µF) and does not require added series ESR for stability. Unlike many older LDOs, it remains unconditionally stable with X5R/X7R ceramics, simplifying BOM and improving transient response.
