Minimum output is 1.233 V, maximum is 10 V, set by the resistor divider ratio. Being a shunt reference, it behaves like a two-terminal Zener: you bias it through a resistor from the supply rail, and the device shunts enough cathode current (80 µA typical) to regulate the output. No separate supply pin — the load and the reference share the same current path. The TO-92-3 through-hole package is the breadboard-friendly, hand-solderable form factor you see on evaluation boards and legacy industrial control cards. The three leads are cathode, anode, and the adjust pin — same pinout as the LM4041 fixed-voltage parts. ## ±0.5% initial tolerance — where it lands in the LM4041 family The 'C' in LM4041CILPE3 marks the ±0.5% initial accuracy grade. That sits between the 'A' grade (±0.1%) and the 'D' grade (±1%). For a 2.5 V output, ±0.5% means ±12.5 mV worst-case at 25 °C — tight enough for an 8-bit ADC reference or a comparator threshold, not tight enough for a 12-bit SAR reference without calibration. If the BOM calls for an LM4041DILP (±1%), the LM4041CILPE3 drops straight in — same pinout, same TO-92-3 package, same operating conditions. The only trade is cost: the tighter bin carries a small premium, but you gain margin on the reference accuracy without a board spin. No last-time-buy notice, no end-of-life window to plan around.","metaTitle":"LM4041CILPE3 Shunt Voltage Reference, Adjustable 1.233V-10V","metaDescription":"LM4041CILPE3 adjustable shunt reference from Microchip Technology.
