THREE TERMINAL POSITIVE VOLTAGE REGULATORS

零件编号(s) : LM317
ESTEK
Estek Electronics Co. Ltd
产品描述 (功能) : 3 - TERMINAL POSITIVE -VOLTAGE REGULATORS

Description
The 3 17 are adjustable 3 - TERMINAL POSITIVE -VOLTAGE REGULATORS capable of supplying 1.5A over a differential VOLTAGE range of 3V to 40V. They are exceptionally easy to use and require only two external resistors to set the output VOLTAGE. Both input and output regulation are better than standard fixed REGULATORS.In addition to higher performance than fixed REGULATORS, these REGULATORS offer full overload protection available only in integrated circuits. Included on the chip are current limit, thermal overload protection, and safe-area protection. All overload protection circuitry remains fully functional even if the adjustment TERMINAL is disconnected. Normally, no capacitors are needed unless the device is situated far from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response.

Features
• Output VOLTAGE Range Adjustable from1.2 Vto 37 V
• Output Current Capability of 1.5 AMax
• Input Regulation Typically 0.01 % Per Input - VoltChange
• Output Regulation Typically 0.1 %
• Peak Output Current Constant Over Temperature Range of Regulator
• Popular 3-Lead TO-220 Package
• Ripple Rejection Typically 80 dB

产品描述 (功能) : 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS

3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS



The LM78XX series of THREE-TERMINAL POSITIVE REGULATORS are available in the TO-220/D-PAK package and with several fixed output VOLTAGEs, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can

deliver over 1A output current. Although designed primarily as fixed VOLTAGE REGULATORS, these devices can be used with external components to obtain adjustable VOLTAGEs and currents.



FEATURES

·Output Current up to 1A

·Output VOLTAGEs of 5, 6, 8, 9, 10, 11, 12, 15, 18, 24V

·Thermal Overload Protection

·Short Circuit Protection

·Output Transistor SOA Protection

3-TERMINAL POSITIVE VOLTAGE REGULATOR

The ML7800 series are 3-TERMINAL POSITIVE VOLTAGE REGULATORS. These REGULATORS employ internal current-limiting, thermal-shutdown and safe-area compensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current (Please refer to the "thermal design" portion of application note). They are intended as fixed VOLTAGE regulations in a wide range of applications including local (on-card) regulation for elimination of distributution problems associated with single point regulation. In addition to use as fixed VOLTAGE REGULATORS, these devices can be used with external components to obtain adjustable output VOLTAGEs and currents.
