Product details
Overview
LT3060ITS8-5#TRPBF from Analog Devices is a 5V fixed-output, micropower low-dropout linear regulator in an 8-lead TSOT-23 package. It delivers 100mA output current with 300mV typical dropout at full load, 40µA quiescent current, and 30µVRMS output noise (10Hz–100kHz), designed for battery-powered and automotive power supplies where ultra-low IQ and high PSRR are critical.
For engineers reviewing the LT3060ITS8-5#TRPBF datasheet, LT3060ITS8-5#TRPBF pinout, LT3060ITS8-5#TRPBF application, or LT3060ITS8-5#TRPBF equivalent, key selection criteria include its 1.6V–45V input range, ±2% output tolerance over line/load/temperature, reverse-battery protection, and guaranteed operation from –40°C to 125°C in the TSOT-23 package.
Technical Context
The LT3060ITS8-5#TRPBF employs a PNP pass transistor architecture enabling low dropout and inherent reverse-battery protection. Its reference soft-start circuit-controlled by a single external capacitor on the REF/BYP pin-reduces output voltage overshoot and lowers integrated noise without requiring additional biasing components.
Stability is optimized for ceramic output capacitors ≥2.2µF with no ESR requirement. Internal foldback current limiting, thermal shutdown, and reverse-current protection operate autonomously without external circuitry, making it suitable for unattended industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±2% over line, load, and –40°C to 125°C - ensures stable MCU core or sensor rail under wide operating conditions. |
| Input Voltage Range | 1.6V to 45V - supports direct connection to automotive batteries (cold-crank down to ~4.5V) and industrial 24V/36V rails without pre-regulation. |
| Max Output Current | 100mA - sufficient for powering microcontrollers, RF transceivers, or analog front-ends in space-constrained portable systems. |
| Quiescent Current | 40µA typical - enables multi-year battery life in always-on IoT sensors and telematics modules. |
| Dropout Voltage | 300mV at 100mA - allows regulation from 5.3V input when output is 5.0V, maximizing usable battery voltage range. |
| Output Noise | 30µVRMS (10Hz–100kHz) - meets low-noise requirements for precision ADC references and RF LDO applications. |
| Shutdown Current | <1µA - enables deep-sleep modes in battery-backed systems without significant leakage drain. |
Pinout & Package
LT3060ITS8-5#TRPBF is housed in an 8-lead Plastic ThinSOT™ (TS8) package (2.9mm × 1.6mm × 0.9mm), thermally enhanced with exposed pad soldered to PCB ground for improved θJA (57°C/W to 67°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown Control Input | Active-low enable; logic threshold 0.3V (off) to 0.8V (on); draws <1µA when asserted low. |
| 2 (GND) | Ground Reference | Main power return path; connects internally to exposed thermal pad - must be soldered to PCB ground plane. |
| 3 (GND) | Ground Reference | Second ground terminal to reduce ground loop impedance and improve PSRR at high frequencies. |
| 4 (GND) | Ground Reference | Third ground terminal supporting low-impedance return for high-frequency noise currents. |
| 5 (IN) | Input Supply | Accepts 1.6V–45V; includes reverse-battery protection - survives –45V input without damage. |
| 6 (OUT) | Regulated Output | Delivers 5.0V ±2%; requires ≥2.2µF ceramic output capacitor for stability and transient response. |
| 7 (ADJ) | Adjust Pin (N/C for fixed version) | No-connect for LT3060ITS8-5#TRPBF; internally tied to internal reference - leave floating or connect to OUT per datasheet guidance. |
| 8 (REF/BYP) | Noise Reduction & Soft-Start | Connects to 10nF capacitor to reduce reference noise and control output ramp rate during startup. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-battery protection | Withstands –45V on IN pin without damage or reverse current flow - eliminates need for external series diode in automotive applications. |
| Single-capacitor soft-start | 10nF on REF/BYP pin controls output rise time and reduces inrush current - simplifies design vs. RC networks or dedicated sequencers. |
| Ceramic capacitor stability | Stable with ≥2.2µF X5R/X7R ceramics - avoids costly tantalum or electrolytic capacitors and improves reliability. |
| Low-noise reference architecture | 30µVRMS noise achieved via internal filtered bandgap and external REF/BYP bypass - suitable for noise-sensitive analog signal chains. |
| Thermal and current foldback protection | Auto-recovery shutdown at 150°C junction; current limit decreases as VIN–VOUT increases - prevents thermal runaway under overload or high-differential conditions. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSM1052-5.0 | 5V fixed, 150mA, 50µA IQ, 400mV dropout, SOT-23-5 package (5-pin, no REF/BYP) | Lacks REF/BYP pin for noise filtering; no reverse-battery protection; lower PSRR (52dB @ 120Hz) | Select when board space is constrained to 5-pin footprint and noise/robustness requirements are relaxed. |

FAQ
What is the maximum input voltage rating for the LT3060ITS8-5#TRPBF?
The LT3060ITS8-5#TRPBF has an absolute maximum input voltage of ±50V on the IN pin. Its operational input range is specified from 1.6V to 45V, allowing reliable use in automotive (load dump up to 40V) and industrial 24V/36V systems. Exceeding 45V may trigger overvoltage protection or degrade long-term reliability.
Does the LT3060ITS8-5#TRPBF require an external capacitor on the ADJ pin?
No - the LT3060ITS8-5#TRPBF is a fixed 5V output variant; the ADJ pin is not used and should be left floating or connected to the OUT pin per Analog Devices' layout guidance. Only the adjustable LT3060 (no suffix) requires an external resistor divider on ADJ.
Can the LT3060ITS8-5#TRPBF be used in AEC-Q100 qualified automotive designs?
Yes - while the standard LT3060ITS8-5#TRPBF is rated for –40°C to 125°C, Analog Devices offers automotive-grade variants (e.g., LT3060ITS8-5#WTRPBF) that are AEC-Q100 qualified and undergo controlled manufacturing for automotive applications. The base part is widely used in non-safety-critical automotive subsystems.
What is the purpose of the REF/BYP pin on the LT3060ITS8-5#TRPBF?
The REF/BYP pin on the LT3060ITS8-5#TRPBF accepts a 10nF capacitor to filter the internal reference voltage, reducing output noise to 30µVRMS and controlling soft-start behavior. This single external component replaces complex RC networks needed in older LDOs to achieve comparable noise performance.
How does the LT3060ITS8-5#TRPBF handle reverse-current conditions?
The LT3060ITS8-5#TRPBF includes integrated reverse-current protection: when the output voltage exceeds the input (e.g., during hot-swap or backup battery scenarios), internal circuitry blocks current flow from OUT to IN, limiting reverse current to ≤10µA - eliminating the need for an external blocking diode.
