Ordering number:ENN2301B
Monolithic Linear IC
LA5665
Multifunction Multiple Voltage Regulator
Overview
* Especially suited for use in micorcomputer-controlled tuners, receivers, preamplifiers and the like.
Package Dimensions
unit:mm 3075-SIP7H
[LA5665]
18.0 3.4 3.0
Features
* Two independent voltage regulators contained in a single chip (15.5V/350mA, 5.6V/100mA). * Reset circuit which delivers the reset signal on the positive transition, negative transition of the 5.6V output. * Muting circuit which detects the 15.5V output and reset output to deliver the muting signal (We have the LA5666 whose detection function for reset, muting is provided on the input voltage side).

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO products(including technical data,services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be expor ted without obtaining the expor t license from the authorities concerned in accordance with the above law.
