Analog Devices Inc. LT3060HTS8#TRPBF

Overview

LT3060HTS8#TRPBF from Analog Devices is a 2.5V fixed-output, micropower low-dropout linear regulator in an 8-lead ThinSOT™ package, delivering 100mA output current with 300mV dropout at full load, 40µA quiescent current, and 30µVRMS output noise (10Hz–100kHz). It serves as a precision, low-noise power supply for automotive sensors and avionic subsystems requiring stable voltage under wide input (1.6V–45V) and high-temperature (–40°C to 150°C) conditions.

For engineers reviewing the LT3060HTS8#TRPBF datasheet, LT3060HTS8#TRPBF pinout, LT3060HTS8#TRPBF application, or LT3060HTS8#TRPBF equivalent, key selection criteria include guaranteed dropout performance at 150°C junction temperature, reverse-battery protection, shutdown current <1µA, and compatibility with low-ESR ceramic capacitors without external ESR requirements.

Technical Context

The LT3060HTS8#TRPBF employs a PMOS pass transistor architecture enabling ultra-low quiescent current and true reverse-battery protection-no external diode needed. Its reference soft-start circuit, controlled by a single REF/BYP capacitor, simultaneously reduces output noise and prevents inrush during power-up.

Internal foldback current limiting and thermal shutdown operate across the full –40°C to 150°C operating junction range, with all protection features fully characterized and tested at 150°C for H-grade qualification. The device maintains ±2% output tolerance over line, load, and temperature without requiring output capacitor ESR for stability.

FAQ

What is the maximum input voltage rating for the LT3060HTS8#TRPBF?

The LT3060HTS8#TRPBF has an absolute maximum input voltage of ±50V on the IN pin, with a functional operating range of 1.6V to 45V. This allows direct integration into 24V and 42V automotive systems, including transient conditions like load dump, without external clamping circuitry. The device also features reverse-battery protection up to –45V, ensuring survivability in incorrect battery connection scenarios.

Does the LT3060HTS8#TRPBF require an external resistor divider to set its output voltage?

No, the LT3060HTS8#TRPBF is a fixed 2.5V output variant; the ADJ pin is internally connected and requires no external resistors. Unlike the adjustable LT3060 version, this part eliminates resistor matching errors and board space for feedback networks - simplifying design and improving long-term output accuracy. The REF/BYP pin still requires a 10nF capacitor for optimal noise and soft-start performance.

How does the LT3060HTS8#TRPBF achieve low noise without increasing output capacitance?

The LT3060HTS8#TRPBF achieves 30µVRMS (10Hz–100kHz) output noise through an integrated reference bypass architecture: a 10nF capacitor on the REF/BYP pin filters the internal bandgap reference and controls soft-start timing. This eliminates the need for large output capacitors or external noise-reduction networks, maintaining low noise while supporting fast transient response with only a 2.2µF ceramic output capacitor.

Is the LT3060HTS8#TRPBF pin-compatible with other LT3060 variants in the TS8 package?

Yes, all LT3060 variants in the TS8 package - including LT3060ETS8#TRPBF, LT3060ITS8#TRPBF, LT3060HTS8#TRPBF, and fixed-voltage versions like LT3060HTS8-2.5#TRPBF - share identical pinout, footprint, and thermal pad layout. This enables drop-in replacement across temperature grades and output voltages without PCB redesign, provided the ADJ pin remains unconnected for fixed-output parts.

What protection features are included in the LT3060HTS8#TRPBF and how are they validated?

The LT3060HTS8#TRPBF integrates reverse-battery protection, reverse-output protection, reverse-current protection, foldback current limiting, and thermal shutdown - all 100% tested at 150°C junction temperature per AEC-Q100. Reverse-output current is limited to ≤10µA at 2.5V, and shutdown current remains <1µA even at 45V input, ensuring fail-safe behavior in fault conditions without external components.
