That ratiometric relationship means the output tracks the input. ## 25 mA output — sizing the load With a 25 mA output rating, this part is sized for auxiliary bias rails, gate-drive supplies, or small-signal circuits — not for powering a relay bank or an MCU core. The single positive output and the 90 kHz switching frequency keep the external capacitor count low, but the load budget must stay under that 25 mA ceiling across the full input range and temperature span. ## Industrial temperature range and package Rated for -40°C to 85°C, the MAX1822ESA+T fits industrial control, outdoor telecom, and automotive cabin environments. The 8-SOIC package (0.154\" width, 3.90 mm body) is a standard surface-mount footprint. ## Lifecycle and sourcing The MAX1822ESA+T carries an Active product status with ROHS3 compliance. There is no last-time-buy pressure and no official successor announced.","metaTitle":"MAX1822ESA+T Charge Pump Regulator, 90 kHz, 25 mA, 8-SOIC","metaDescription":"Maxim MAX1822ESA+T charge pump regulator, fixed Vin+11V output, 25 mA, 90 kHz, 8-SOIC, -40°C to 85°C.
