austriamicrosystems Launches AS1369 Ultra Low Dropout Regulator

austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of high performance analog ICs for communications, industrial, medical and automotive applications, has launched the AS1369 ultra-low dropout regulator with a guaranteed 200mA output current. The AS1369 has been specifically designed for all space critical applications such as mobile phones and PDAs which require high performance despite limited PCB space.

austriamicrosystems AS1369 Ultra Low Dropout Regulator Block DiagramWith an operating input voltage between 2V and 5.5V, the AS1369 is ideal for dual or triple standard-cell and single Li-Ion cell battery powered applications and is available in a variety of pre-programmed output voltages from 1.2V to 5.0V. The output voltage is regulated with an accuracy of 0.7% which meets the requirements of today’s portable battery-powered products. With a low dropout voltage of 40mV @ 100mA, 80mV @ 200mA, an extremely low quiescent current of only 25uA during operation and an exceptional 5nA during shutdown, battery life time is maximized.

“austriamicrosystems’ AS1369 fulfills the requirements of slim and compact modern designs where PCB space is very limited and must be used efficiently. Improved performance and maximized battery lifetime are the additional benefits of this LDO,” said Walter Moshammer, marketing director Standard Linear at austriamicrosystems. “With only 1mm2 PCB space required and the ability to work with the smallest sized capacitors, the AS1369 offers superior performance for all space sensitive applications.”

The AS1369 allows the use of a small 1uF ceramic output capacitor and features a PSRR performance of 80dB at 1kHz and 56dB at 100kHz. No external bypass capacitor is needed and, combined with the exceptional low noise performance of only 30uVrms between 400Hz and 80kHz, the AS1369 is ideally suited for noise sensitive wireless and RF applications.

A digital enable input with a turn-on time of only 30us allows dynamic power management in a system. In addition, the AS1369 offers over-temperature and over-current protection. The 4-bump WL-CSP package with dimensions of only 1mm2 is 9 times smaller than a standard SOT23 package.
