Product details
Overview
LTC1258CMS8-2.5#TRPBF from Analog Devices (formerly Linear Technology) is a micropower, low-dropout 2.5V bandgap voltage reference IC in an 8-pin MSOP package. It delivers 2.5V output with ±0.1% initial accuracy (0.15% max), 40ppm/°C max temperature drift, and only 4μA typical quiescent current. Its 200mV max dropout at 10mA makes it ideal for battery-powered precision analog systems such as portable data acquisition and handheld instrumentation.
For engineers reviewing the LTC1258CMS8-2.5#TRPBF datasheet, LTC1258CMS8-2.5#TRPBF pinout, LTC1258CMS8-2.5#TRPBF application, or LTC1258CMS8-2.5#TRPBF equivalent, key selection criteria include ultralow supply current, no-output-capacitor stability, ±2mA sink capability, and MSOP-8 footprint compatibility with space-constrained PCB layouts.
Technical Context
The LTC1258CMS8-2.5#TRPBF uses curvature-compensated bandgap architecture with trimmed thin-film resistors to achieve low drift and high accuracy. Its internal P-channel MOSFET pass transistor enables true low-dropout operation and eliminates the high quiescent current penalty of saturated PNP-based references.
It operates across 2.7V to 12.6V input range, supports sourcing up to 10mA and sinking up to 2mA, and remains stable with 0–1μF output capacitance - eliminating need for bypass caps in fast-settling or area-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V nominal, ±0.1% typical initial accuracy (2.4948V–2.5052V at 25°C) |
| Quiescent Current | 4μA typical - enables multi-year battery life in always-on sensor nodes |
| Max Dropout Voltage | 200mV at 10mA load - allows operation down to 2.7V supply for 2.5V output |
| Temp Coefficient | 40ppm/°C max (0°C to 70°C) - ensures ≤±1mV drift over industrial ambient range |
| Load Regulation | 0.1mV/mA sourcing, 1.75mV/mA sinking - maintains tight regulation under dynamic load steps |
| Output Capacitance | Stable with 0–1μF - eliminates mandatory bypass cap, saving board area and cost |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1461CS8-2.5#PBF | Lower 3ppm/°C max drift, higher 100μA quiescent current, SO-8 only | Better long-term stability but unsuitable for ultra-low-power battery systems | Select when drift-critical metrology outweighs battery life; not drop-in due to higher IQ and different package |
| LT1634CS8-2.5#PBF | Shunt topology, 60μA IQ, 25ppm/°C drift, SO-8 package | Requires external current-setting resistor; better for fixed-voltage, non-battery applications | Choose for cost-sensitive industrial supplies where board space allows resistor + shunt layout |

FAQ
What is the maximum input voltage rating for LTC1258CMS8-2.5#TRPBF?
The absolute maximum input voltage for LTC1258CMS8-2.5#TRPBF is 13V. The recommended operating input range is 2.7V to 12.6V, with a minimum headroom of 0.2V above the 2.5V output to maintain regulation. Exceeding 13V may cause permanent damage per Absolute Maximum Ratings.
Does LTC1258CMS8-2.5#TRPBF require an output bypass capacitor?
No, LTC1258CMS8-2.5#TRPBF is stable with 0μF output capacitance and does not require an external bypass capacitor. It remains stable with up to 1μF, enabling flexibility for fast-settling applications or space-constrained layouts where capacitors are omitted.
Can LTC1258CMS8-2.5#TRPBF sink current, and how much?
Yes, LTC1258CMS8-2.5#TRPBF can sink up to 2mA while maintaining regulation. This capability supports active pull-down in precision comparator circuits, DAC output buffering, and virtual ground generation - unlike many series references limited to sourcing only.
What is the temperature coefficient specification for LTC1258CMS8-2.5#TRPBF over its full operating range?
LTC1258CMS8-2.5#TRPBF has a maximum temperature coefficient of 40ppm/°C over the specified 0°C to 70°C range. Over the wider operating range (–40°C to 100°C), drift increases to 60ppm/°C, as confirmed in the Electrical Characteristics table for the MS8 package.
Is LTC1258CMS8-2.5#TRPBF pin-compatible with other variants in the LTC1258 family?
Yes, all LTC1258 variants (e.g., LTC1258CMS8-3#TRPBF, LTC1258CMS8-5#TRPBF) share identical MSOP-8 pinout and footprint. Pin functions - including OUT, IN, DNC, and GND - are identical across fixed-output versions; only the trimmed output voltage differs.
