200mA Low Dropout Voltage Linear Regulator
The DS8603 series are a group of low-dropout ( LDO ) voltage regulators offering the benefits of wide input voltage range, low dropout voltage, low power consumption, and miniaturized packaging. Quiescent current of only 2.2µA makes these devices ideal for powering the battery-powered, always-on systems that require very little idle-state power dissipation to a longer service life. There is an option of shutdown mode by selecting the parts with the EN pin and pulling it low. The shutdown current in this mode goes down to only 10nA ( typical ). The DS8603 series of linear regulators are stable with the ceramic output capacitor over its wide input range from 2V to 55V and the entire range of o...

130/225 MHz Low Power Dual Modulus Prescalers
The DS8615 series products are low power dual modulus prescalers which divide by 32 33 and 40 41 respectively The modulus control (MC) input selects division by N when at a high TTL level and division by N a 1 when at a low TTL level The clock inputs are buffered providing 40 100 mVrms input sensitivity The two outputs provide the user the option to wire either a totem-pole or open-collector output structure Additionally the user can wire a resistor between the two output pins to minimize edge transition emissions The outputs are designed to drive positive edge triggered PLLs These products can be operated from either an unregulated 5 5V to 13 5V source or regulated 5V g 10% source Unregulat...
