Key Features
- 40V maximum input voltage rating supporting wide input range from automotive 12V/24V rails and industrial 24V to 36V bus supplies
- 200 mA output current with only 420 mV maximum dropout voltage at full load for efficient high-voltage LDO regulation
- Ultra-low noise output suitable for powering precision ADCs, DACs, and analog front-end circuits sensitive to supply ripple
- Operating temperature range of -40°C to +125°C covering full industrial and automotive ambient conditions
- Tiny 6-pin SOT-23 package minimizing PCB area for distributed point-of-load regulation near sensitive analog circuits
Applications
The ADP7142ACPZN-3.3 provides a clean 3.3V regulated output from high-voltage industrial and automotive supply rails up to 40V, making it ideal for powering precision analog circuits near motor drivers, industrial sensors, and 24V PLC I/O modules. Its ultra-low noise output protects sensitive ADC reference pins and op-amp supply rails from switching regulator-induced ripple. The 6-pin SOT-23 footprint allows distributed placement on high-voltage PCBs where local analog supply decoupling is critical.

Frequently Asked Questions
What is the maximum input voltage of the ADP7142, and which supply rails can it regulate from?
The ADP7142 accepts input voltages up to 40V, covering automotive 12V and 24V rails, industrial 24V and 36V bus supplies, and even 48V telecom rails when the input exceeds the 40V limit only transiently. The 4.3V minimum input combined with 3.3V output means only 1V headroom is needed below the maximum range.
How much dropout voltage does the ADP7142 exhibit at its full 200 mA load current?
The ADP7142 has a maximum dropout voltage of 420 mV at 200 mA output current, meaning a 3.72V input minimum is needed to regulate 3.3V output at full load. This low dropout makes it efficient even when the input supply voltage is close to the 3.3V output, minimizing power dissipation in the LDO pass transistor.
Is the ADP7142 suitable for powering precision ADC reference circuits that require low supply noise?
Yes, the ADP7142 is designed for precision analog applications and provides ultra-low output noise, typically below 20 µV RMS across the 10 Hz to 100 kHz band. This low noise floor preserves ADC dynamic range and prevents reference voltage corruption from switching converter harmonics present on high-voltage input rails.
What temperature range does the ADP7142ACPZN-3.3 cover, and is it rated for automotive use?
The ADP7142ACPZN-3.3 is rated from -40°C to +125°C junction temperature, covering the full industrial temperature range and most automotive interior ambient conditions. Combined with the 40V input rating, this makes it suitable for automotive body electronics and industrial field instruments operating in harsh thermal environments.
How compact is the ADP7142's 6-pin SOT-23 package for distributed analog power design?
The 6-pin SOT-23 package measures approximately 1.9 mm x 2.8 mm with 0.95 mm pin pitch, one of the smallest available LDO footprints for a 200 mA regulator. This enables placement of the ADP7142 immediately adjacent to sensitive analog ICs on high-voltage PCBs, minimizing the distance between regulator and load to reduce output impedance effects.
