• Low 85µA Quiescent Supply Current
• Low 1nA Current Shutdown Mode
• Stable with 1µF C_OUT
• PSRR > 60dB at 100Hz
• Thermal Overload Protection
• Short-Circuit Protection
• -5.0V, -3.0V, or -2.5V Output Voltage or Adjustable (-1.25V to -5.5V)
• Tiny SOT23-5 Package

The MAX1735 negative-output, low-dropout linear regulator operates from a -2.5V to -6.5V input and delivers a guaranteed 200mA with a low 80mV dropout. The high-accuracy (±1%) output voltage is preset or can be adjusted from -1.25V to -5.5V with an external resistive voltage-divider.

An internal N-channel MOSFET allows for a low 85µA quiescent current virtually independent of the load, making this device ideal for battery-powered portable equipment, such as PDAs, mobile phones, cordless phones, and wireless data modems.

The device is available in several preset output voltage versions: -5.0V, -3.0V, and -2.5V. All versions offer a 1nA low-power shutdown mode, short-circuit protection, and thermal overload protection. The device is offered in a tiny 5-pin SOT23 package.
