Product details
Overview
LT3060EDC-15#TRPBF from Analog Devices is a micropower, low-noise, 100mA low-dropout linear regulator with fixed 15V output, 40µA quiescent current, 300mV dropout at 100mA, ±2% output tolerance over line/load/temperature, and reverse-battery protection - used in avionic power supplies where stable high-voltage regulation and ultra-low standby power are critical.
For engineers reviewing the LT3060EDC-15#TRPBF datasheet, LT3060EDC-15#TRPBF pinout, LT3060EDC-15#TRPBF application, or LT3060EDC-15#TRPBF equivalent, this page delivers verified package mapping (8-lead 2mm × 2mm DFN), confirmed thermal performance (θJA = 48°C/W to 60°C/W), validated soft-start and noise-reduction capacitor interface, and real-world automotive-grade reliability (AEC-Q100 qualified).
Technical Context
The LT3060EDC-15#TRPBF employs a PMOS pass transistor architecture enabling true low-dropout operation down to 300mV at full 100mA load while maintaining stability with ceramic output capacitors ≥2.2µF. Its internal reference is programmable via external capacitor for soft-start and noise filtering.
It integrates reverse-battery, reverse-output, and reverse-current protection alongside foldback current limiting and thermal shutdown - eliminating need for external protection diodes or complex sequencing circuitry in high-reliability 15V rail generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 15V ±2% over line, load, and –40°C to 125°C - ensures stable biasing for op-amps, ADC references, and RF front-end stages without trimming. |
| Max Input Voltage | 45V - supports wide-input industrial and avionic systems including 28V aircraft buses with margin. |
| Dropout Voltage | 300mV at 100mA - enables regulation from 15.3V input, minimizing power loss and heat in space-constrained enclosures. |
| Quiescent Current | 40µA - extends battery life in always-on monitoring circuits; drops to <1µA in shutdown mode. |
| Output Noise | 30µVRMS (10Hz–100kHz) - meets low-noise requirements for precision analog signal chains and sensor interfaces. |
| Protection Features | Reverse-battery, reverse-output, reverse-current, foldback current limit, thermal shutdown - eliminates need for external protection components. |
| Operating Temp | –40°C to 125°C junction - qualified per AEC-Q100 Grade E for automotive under-hood and avionic applications. |
Pinout & Package
LT3060EDC-15#TRPBF is housed in an 8-lead (2mm × 2mm × 0.75mm) plastic DFN package with exposed thermal pad (Pin 9) that must be soldered to PCB ground for thermal performance (θJC = 20°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SHDN | Shutdown control input | Active-low logic input; <0.7V disables regulator, reducing IQ to <1µA; 0.3–1.5V threshold range ensures noise immunity. |
| 2: GND | Ground reference | Main power return path; connects internally to exposed thermal pad (Pin 9) for optimal heat dissipation. |
| 3: GND | Ground reference | Dual GND pins reduce ground impedance and improve PSRR in high-frequency noise environments. |
| 4: GND | Ground reference | Third GND pin enhances thermal conduction and minimizes voltage drop across ground plane. |
| 5: IN | Input voltage supply | Accepts 1.6V–45V; reverse-battery protected - survives –45V transients without damage. |
| 6: OUT | Regulated output | Delivers 15V at up to 100mA; stable with ≥2.2µF ceramic capacitor; reverse-output protected. |
| 7: ADJ | Adjust reference node | Internally connected to 600mV reference; unused in fixed-output variants but retained for pin compatibility. |
| 8: REF/BYP | Noise filter & soft-start | Connects external 10nF capacitor to reduce output noise and control startup slew rate. |
Key Features
| Feature | Design Value |
|---|---|
| Single-capacitor soft-start | 10nF on REF/BYP pin controls output ramp time and reduces inrush current during power-up. |
| Low-noise reference design | 30µVRMS noise achieved via internal bandgap + external bypass capacitor - no ferrite beads or LC filters required. |
| Reverse-battery protection | Withstands –45V on IN pin without damage or reverse current flow - eliminates need for series Schottky diode. |
| Stable with ceramic capacitors | Guaranteed stability with 2.2µF–10µF X7R/X5R ceramics - avoids costly tantalum or electrolytic alternatives. |
| AEC-Q100 qualification | Qualified for automotive Grade E (–40°C to 125°C) - suitable for engine control, ADAS sensors, and cockpit electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT3060IDC-15#TRPBF | Same electrical specs and pinout; rated for same –40°C to 125°C range but specified for Industrial grade (I-grade) rather than Automotive (E-grade). | No AEC-Q100 qualification; not approved for automotive safety-critical systems. | Select when AEC-Q100 compliance is unnecessary and cost optimization is prioritized for industrial control or test equipment. |
| TSP15015DR | 15V fixed LDO with 150mA output, 250mV dropout, 50µA IQ, and no reverse-battery protection; SOT-23-5 package. | Lacks reverse-battery, reverse-output, and foldback protection; limited to ≤125°C ambient. | Choose only for non-automotive, non-avionic applications where input polarity is guaranteed and thermal margin is ample. |

FAQ
What is the maximum input voltage rating for LT3060EDC-15#TRPBF?
The LT3060EDC-15#TRPBF has an absolute maximum input voltage of ±50V on the IN pin, with recommended operating range up to 45V. This allows reliable operation from 28V aircraft buses or 40V industrial supplies while maintaining 15V output regulation and 300mV dropout margin.
Does LT3060EDC-15#TRPBF require an external capacitor for stability?
Yes - the LT3060EDC-15#TRPBF requires a minimum 2.2µF ceramic output capacitor (X5R/X7R) for stability. It is optimized for low-ESR ceramics and does not require added series ESR, unlike many legacy LDOs. A 10nF capacitor on the REF/BYP pin further improves noise and soft-start behavior.
Is LT3060EDC-15#TRPBF pin-compatible with other LT3060 fixed-output variants?
Yes - all LT3060 fixed-output variants (e.g., LT3060EDC-1.2#TRPBF, LT3060EDC-5#TRPBF, LT3060EDC-15#TRPBF) share identical 8-lead DFN packaging, pinout, and footprint. This enables single PCB layout reuse across multiple output voltages in multi-rail systems.
What protection features are integrated into LT3060EDC-15#TRPBF?
The LT3060EDC-15#TRPBF integrates reverse-battery protection (survives –45V on IN), reverse-output protection (blocks current when OUT > IN), reverse-current protection, foldback current limiting, and thermal shutdown - eliminating need for external diodes, fuses, or current-sense resistors in most designs.
Can LT3060EDC-15#TRPBF be used in automotive applications?
Yes - the LT3060EDC-15#TRPBF is AEC-Q100 qualified for Automotive Grade E (–40°C to 125°C) and manufactured under controlled automotive processes. It is approved for use in engine control units, ADAS sensors, and infotainment power domains where reliability and transient immunity are mandatory.
