The MAX8902A/MAX8902B are high-PSRR, ultra-low-noise, low-dropout (LDO) linear regulators that deliver 500mA.
The industry's smallest low-noise, LDO regulators, these devices offer superior performance while saving board space.
Packaged in a tiny, 2mm x 2mm TDFN, the MAX8902A/MAX8902B feature a low, 100mV (max) dropout at full load (500mA), 16µVRMS output noise, and 92dB PSRR (at 5kHz).
The small size and high performance of the MAX8902A/MAX8902B make them ideal for battery-operated applications, such as ultra-mobile/notebook PCs, smartphones, PDAs, portable media players, and GPS devices.
SUNNYVALE, CA—December 4, 2007—Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX8902A/MAX8902B, the industry's smallest 500mA, low-noise, low-dropout (LDO) linear regulators. Packaged in a tiny, 2mm x 2mm TDFN, these devices provide up to 92dB PSRR (at 5kHz), 16µVRMS output noise, and a low, 100mV (max) dropout voltage at full load (500mA). The MAX8902A/MAX8902B are ideal for noise-sensitive and space-constrained applications, such as smartphones, PDAs, PMP/MP3 players, GPS devices, and ultra-mobile/notebook PCs.
The MAX8902A/MAX8902B offer ±1.5% output-voltage accuracy and a wide, 1.7V to 5.5V input-voltage range. The MAX8902A features preset pin-selectable output voltages between 1.5V and 4.7V, and the MAX8902B allows users to adjust the output voltage between 0.6V and 5.3V using two external resistors. To maximize battery life, these devices consume a low, 80µA operating current and less than 1µA shutdown current. Other features include a programmable soft-start circuit to prevent high inrush currents, short-circuit protection, reverse-current protection, and thermal shutdown.
Available in a thermally enhanced, 2mm x 2mm, 8-pin TDFN package, the MAX8902A/MAX8902B are fully specified over the -40°C to +125°C automotive temperature range. Prices start at $1.25 (1000-up, FOB USA).
