CCD191 - 6000 Element Linear Image Sensor

Fairchild 2008/09/22 09:20

GENERAL DESCRIPTION
The CCD191 is a 6000 element line image sensor designed for scanning applications which require very high resolution, high sensitivity and very wide dynamic range.
Incorporation of on-chip anti-blooming and integration controls allow the CCD191 to be extremely useful in industrial measurement and control environments, or in environments where lighting conditions are difficult to control.
The CCD191 is a third generation device having an overall improved performance compared with first and second generation devices, including enhanced blue response and excellent low light level performance. The photoelement size is 10μm (0.39 mils) x 10μm (0.39 mils) on 10μm (0.39 mils) centers. The device is manufactured using Fairchild Imaging’s advanced chargecoupled device n-channel isoplanar buried-channel technology.

APE8953 - 3A ULTRA LOW DROPOUT LINEAR REGULATOR

Advanced Power Electronics 2008/09/12 09:08

DESCRIPTION
The APE8953 is a 3A ultra low dropout linear regulator.
The product is specifically designed to provide well supply voltage for front side bus termination on motherboard and NB applications. The IC needs two supply voltages, a voltage for the circuitry and a main supply voltage for power conversion to reduce power dissipation and provide extremely low dropout. The APE8953 integrates many functions. A Power-on-Reset(POR) circuit monitors both supply voltage to prevent wrong operations. A thermal shutdown and current limit functions protect the device against thermal and current over-load. A POK indicates the output status with time delay which is set internally. It can control other converter for power sequence. The APE8953 can be enabled by other power system. Pulling and holding
the EN pin below 0.4V shuts off the output.
The APE8953 is available in ESOP-8 package which features small size as SO-8 and exposed pad to reduce the junction-to-case resistance, being applicable in 2~3W applications.

FEATURES
*Ultra Low Dropout Voltage 250mV at 3A Output Current
*Low ESR Output Capacitor (MLCC) Applicable
*0.8V Reference Voltage
*Fast Transient Response
*Current Limit and Thermal Shutdown Protection
*Adjustable Output Voltage by External Resistors
*Power-on-Reset Monitoring on Both VCNTL and VIN Pins
*Under Voltage Protection
*Power OK Output with a Delay Time
*Internal Soft-Start
*SOP-8 with Exposed Pad Package
*RoHS Compliant & Halogen Free

SGM2022 - Dual, Low Dropout, 150mA RF - Linear Regulators

ETC 2008/03/14 10:11

GENERAL DESCRIPTION
The SGM2022 is a dual, low-power, low-dropout, CMOS linear voltage regulators.
It operates from a 2.5V to 4.5V input and delivers up to 150mA at each channel.
The SGM2022 is the perfect choice for low voltage, low power and RF applications.
