2.545V fixed reference with ±1% accuracy
This is a series voltage reference with a fixed 2.545V output — a value chosen for battery charger feedback loops where the target voltage needs to sit just above the standard 2.5V bandgap. The ±1% tolerance means the output stays within 25 mV of nominal across the operating range, tight enough for most constant-voltage charging profiles without external trimming. Input voltage spans 4.5V to 28V, so it works off a 5V rail, a 12V supply, or a 24V industrial bus without a pre-regulator. The 1 mA output current drives the feedback divider or optocoupler LED in a typical isolated supply.
Temperature range and compliance
Rated for 0°C to 105°C ambient — covers most indoor industrial and consumer gear. Not specified for -40°C cold start, so leave margin if the board sees a freezer or outdoor enclosure. ROHS3 compliant, no exemptions.
