VPS6001

VPS6001 is a linear regulator capable of withstanding ultra-high input voltages, with continuous operation up to 100V input and transient voltage tolerance up to 115V. Combined with the ESOP8 package's superior thermal dissipation, it can deliver wide-range transient high currents at high input voltages, meeting the short-duration dynamic high-current demands of microprocessors. The key feature of the VPS6001 is its dual-stage output: VO1 and VO2. VO1 uses the high-voltage VIN as its input supply, while VO2 uses VO1 as its input supply. This enables integration with a switching power supply — when the switcher is active, energy is fed back to VO1, allowing the ultra-high-voltage linear regulator from VIN to VO1 to shut down automatically, improving overall system efficiency. When the switching power supply is inactive, the ultra-high-voltage linear regulator resumes operation, achieving ultra-low standby power consumption. The VPS6001 is stable with ceramic capacitors, minimizing board space. Integrated thermal shutdown and current limiting provide system protection under fault conditions. The ESOP8 package operates over a temperature range of -40°C to 125°C.
