MAX1598
Low-Noise, Low-Dropout, 200mA Linear Regulator
Part Details
- 200mA Output Current
- Low Output Noise: 30µVRMS
- Low 55mV Dropout at 50mA Output
- Low 85µA No-Load Supply Current
- Low 100µA Operating Supply Current, Even in Dropout
- Thermal-Overload and Short-Circuit Protection
- Reverse Battery Protection
- Output Current Limit
- Preset Output Voltages
- 10nA Logic-Controlled Shutdown
The MAX1598 low-noise, low-dropout linear regulator operates from a 2.5V to 6.5V input and delivers up to 200mA. Typical output noise is 30µVRMS, and typical dropout is only 236mV at 200mA. The output voltage is preset to voltages from 2.5V to 5V in 100mV increments.
Designed with an internal P-channel MOSFET pass transistor, the MAX1598 maintains a low 100µA supply current independent of the load current and dropout voltage. Other features include a 10nA logic-controlled shutdown mode, short-circuit and thermal-shutdown protection, and reverse battery protection. The device also includes an autodischarge function, which actively discharges the output voltage to ground when the device is placed in shutdown. The MAX1598 comes in a thin 5-pin SOT23 package.
