Small claims for 500mA LDOs
Compact low-noise low-dropout regulators are ideal for sensitive and space-constrained applications.
Maxim Integrated Products reckons the MAX8902A and MAX8902B are the industry's smallest 500mA low-noise low-dropout (LDO) linear regulators Packaged in tiny 2mm-square TDFNs, these devices provide up to 92dB PSRR (at 5kHz), 16uV RMS output noise, and a low 100mV (maximum) dropout voltage at full load (500mA)

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
The MAX8902A and MAX8902B are ideal for noise-sensitive and space-constrained applications, such as smartphones, PDAs, PMP/MP3 players, GPS devices and ultramobile/notebook PCs.
The MAX8902A and MAX8902B offer +/-1.5% output-voltage accuracy and a wide, 1.7 to 5.5V input-voltage range.
The MAX8902A features preset pin-selectable output voltages between 1.5 and 4.7V, and the MAX8902B allows users to adjust the output voltage between 0.6 and 5.3V using two external resistors.
To maximise battery life, these devices consume a low, 80uA operating current and less than 1uA shutdown current.
Other features include a programmable soft-start circuit to prevent high inrush currents, short-circuit protection, reverse-current protection and thermal shutdown.
In thermally enhanced 2 x 2mm 8-pin TDFN packages, the MAX8902A and MAX8902B are fully specified over the -40 to +125C automotive temperature range.
Prices start at US $1.25 (1000-up).
