Description
SIT3485ESA is a high-efficiency, low-dropout (LDO) voltage regulator from ROHM Semiconductor, designed for stable power supply in compact electronic devices. It features:
- Low dropout voltage (150mV at 150mA) for efficient operation.
- Ultra-low quiescent current (1µA typical), ideal for battery-powered applications.
- High output accuracy (±1%) and low noise, ensuring reliable performance.
- Built-in protections (overcurrent, thermal shutdown).
- Small package (SOT-23-5), suitable for space-constrained designs.
Commonly used in IoT, wearables, and portable electronics, SIT3485ESA balances power efficiency with compactness.
Equivalent
- MAX3485ESA (Maxim Integrated)
- SN65HVD72 (Texas Instruments)
- ADM3485ARZ (Analog Devices)
- SP3485EN-L/TR (Exar/Sipex)
These chips offer comparable functionality (3.3V, half-duplex, up to 10Mbps) and pin compatibility in SOIC-8 packages. Verify datasheets for exact specifications.
