Product details
Overview
LT1460CCMS8-2.5#TRPBF from Analog Devices (formerly Linear Technology) is a micropower precision series voltage reference delivering 2.5V output with ±0.10% initial accuracy, 20ppm/°C max temperature coefficient, and 130µA max supply current in an 8-lead MSOP package. It supplies up to 20mA load current with 0.9V min input-output differential, enabling use in low-voltage, battery-powered precision regulators and data converters.
For engineers reviewing the LT1460CCMS8-2.5#TRPBF datasheet, LT1460CCMS8-2.5#TRPBF pinout, LT1460CCMS8-2.5#TRPBF application, or LT1460CCMS8-2.5#TRPBF equivalent, this device is selected for high-accuracy, low-drift, low-power analog signal conditioning where stable 2.5V biasing, ADC/DAC reference, or trimming is required across 0°C to 70°C.
Technical Context
The LT1460CCMS8-2.5#TRPBF uses curvature-compensated bandgap architecture to achieve low thermal drift and trimmed thin-film resistors for tight initial tolerance. Its internal circuitry eliminates need for external output compensation capacitors while maintaining stability with capacitive loads up to 1µF.
It operates from VOUT + 0.9V to 30V input, supports sourcing only (no sinking), and features reverse-battery protection - it draws no current under −15V reverse input, preventing damage in automotive or portable systems with polarity risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V ±0.10% (2.4975V to 2.5025V) - ensures ≤2.5mV absolute error at 25°C for 12-bit+ converter reference |
| Temp Coefficient | 20ppm/°C max - contributes ≤0.5mV drift over 0°C–70°C ambient range |
| Supply Current | 130µA max - enables >10-year battery life in 10µA-sleep IoT sensor nodes |
| Load Current | 20mA max sourcing - sufficient to drive SAR ADC reference inputs and op-amp bias networks |
| Dropout Voltage | 0.9V min (IOUT = 0) - allows operation from 3.4V supply, compatible with Li-ion single-cell systems |
| Line Regulation | 35ppm/V max (VIN ≥ VOUT + 2.5V) - maintains <0.09mV change per volt input variation |
| Noise (0.1–10Hz) | 10µVP-P - low enough for 16-bit ADCs without additional filtering |
Pinout & Package
LT1460CCMS8-2.5#TRPBF is housed in an 8-lead MSOP (MS8) package with exposed pad (not electrically connected). Pin 1 = VIN, Pin 2 = VOUT, Pin 3 = GND; Pins 4–8 are internally connected no-connects - external circuitry must not be attached.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Positive Input Supply | Accepts 3.4V–30V; minimum 0.9V above VOUT for regulation |
| 2 (VOUT) | Regulated Output | 2.5V reference source; stable with 0–1µF capacitive loads |
| 3 (GND) | Analog Ground Reference | Must be low-impedance return path; separates from digital ground |
| 4–8 | No Connect (Internally Tied) | Not usable; floating or driven connections may cause malfunction |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Enables space-constrained PCB layouts and eliminates capacitor aging/reliability concerns in medical or aerospace designs |
| Reverse battery protection | Withstands −15V input without conduction or latch-up - critical for field-serviceable battery compartments |
| Curvature-compensated bandgap | Delivers 20ppm/°C max drift over full 0°C–70°C range without external trimming |
| Low thermal regulation | 2.5ppm/mW typical - minimizes output shift during load transients in sealed enclosures |
| Stable with capacitive loads | Operates reliably with 0–1µF ceramic or tantalum output capacitance - simplifies EMI filtering design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF192GS-2.5 | 2.5V, ±0.1% initial accuracy, 15ppm/°C, 1.2mA supply current, SO-8 | Higher quiescent current limits battery life; requires output capacitor for stability | Choose when lower tempco is prioritized over power; verify layout supports required 1µF output cap |
| MAX6126AASA25+ | 2.5V, ±0.06% initial accuracy, 3ppm/°C, 120µA supply current, SO-8 | Superior accuracy and drift but higher cost; no reverse-battery protection | Choose for metrology-grade systems where 3ppm/°C drift justifies premium; add external reverse-polarity diode if needed |

FAQ
What is the maximum load current supported by the LT1460CCMS8-2.5#TRPBF?
The LT1460CCMS8-2.5#TRPBF supports up to 20mA of sourcing current. It is not designed to sink current. This capability allows direct driving of ADC reference inputs, op-amp bias networks, and small logic interfaces without external buffers. Exceeding 20mA may degrade output accuracy or cause thermal shutdown.
Does the LT1460CCMS8-2.5#TRPBF require an output capacitor for stability?
No, the LT1460CCMS8-2.5#TRPBF is internally compensated and remains stable with 0–1µF capacitive loads - including ceramic, tantalum, and electrolytic types. This eliminates the need for external output capacitors, reducing BOM count and PCB area. Adding >1µF may induce ringing unless isolated with a small series resistor (≤2Ω).
What is the input voltage range for the LT1460CCMS8-2.5#TRPBF?
The LT1460CCMS8-2.5#TRPBF operates with input voltages from (VOUT + 0.9V) = 3.4V minimum up to 30V maximum. At 3.4V input, it delivers full 2.5V output with specified accuracy and load regulation. Operation below 3.4V results in dropout and unregulated output.
Is the LT1460CCMS8-2.5#TRPBF protected against reverse battery connection?
Yes, the LT1460CCMS8-2.5#TRPBF features built-in reverse-battery protection. When subjected to −15V on VIN with respect to GND, it draws less than 10µA and sustains no damage - a key reliability feature for field-replaceable battery systems in portable test equipment and industrial sensors.
What is the long-term stability specification for the LT1460CCMS8-2.5#TRPBF?
The LT1460CCMS8-2.5#TRPBF exhibits 40ppm/√kHr long-term stability in the MSOP package. This means output drift accumulates slowly over time - approximately 40ppm after 1000 hours, ~57ppm after 2000 hours - and is further reduced by preconditioning (100–200h at 125°C). Board-level stress can influence actual performance.
