The MAX8840ELT40+ from Analog Devices is a high-performance LDO delivering a fixed 4V output at up to 150mA. With an ultra-low dropout of 0.12V at 120mA and excellent PSRR of 78dB at 1kHz, it ensures clean, stable power for noise-sensitive circuits. The 90µA quiescent current balances efficiency with performance. Packaged in a miniature 6-uDFN (1.5x1mm), it is ideal for compact portable electronics.
- Excellent Noise Rejection: 78dB PSRR at 1kHz protects sensitive loads from supply ripple.
- Ultra-Low Dropout: 0.12V at 120mA maximizes efficiency in battery applications.
- Miniature Package: 6-uDFN (1.5x1mm) enables ultra-compact designs.
- High Stability: Fixed 4V output with fast transient response for dynamic loads.
Noise-Sensitive RF Power
78dB PSRR at 1kHz filters supply noise for VCOs and PLLs in communication systems, ensuring clean frequency synthesis.
Battery-Powered Audio
Low dropout (0.12V) maintains 4V rail for audio codecs, preventing distortion as battery voltage sags.
Portable Instrumentation
High PSRR and 150mA output power precision ADC references in handheld multimeters and data loggers.
Wireless Modules
Stable 4V supply for GSM/GPS modules with fast transient response during transmit bursts.
Medical Wearables
Tiny 6-uDFN package (1.5x1mm) fits hearing aids and continuous glucose monitors requiring minimal footprint.
Automotive Sensors
Wide input tolerance and low noise support tire pressure sensors and engine control units.
