Functional Description TLE 4267 is a 5-V low-drop voltage regulator in a TO220-7 package. It supplies an output current of > 400 mA. The IC is shortcircuit-proof and incorporates temperature protection that disables the IC at overtemperature.
Features ● Output voltage tolerance ≤ ± 2 % ● Low-drop voltage ● Very low standby current consumption ● Input voltage up to 40 V ● Overvoltage protection up to 60 V (≤ 400 ms) ● Reset function down to 1 V output voltage ● ESD protection up to 2000 V ● Adjustable reset time ● On/off logic ● Overtemperature protection ● Reverse polarity protection ● Short-circuit proof ● Wide temperature range ● Suitable for use in automotive electronics
Application The IC regulates an input voltage VI in the range 5.5 V < VI < 40 V to VQrated = 5.0 V. A reset signal is generated for an output voltage VQ of < 4.5 V. The reset delay can be set with an external capacitor. The device has two logic inputs. It is turned-ON by a voltage of > 4 V on E2 by the ignition for example. It remains active as a function of the voltage on E6, even if the voltage on E2 goes Low. This makes it possible to implement a self holding circuit without external components. When the device is turned-OFF, the output voltage drops to 0 V and current consumption tends towards 0 µA.
This Sony cell is a bit of a departure for me - IMR cells aside - as it is obviously a bare laptop cell, or possibly for power tool use, and has not been converted in any way for use in lights. So no protection circuit, no button, no aftermarket wrapping, and the stock wrap does not extend to the bottom of the cell. It is common for cells that are intended for use in packs to have an entirely bare base in order to make welding/soldering the cells together easier to do.
The NTE5498 and NTE5499 silicon controlled rectifiers are high performance glass passivated PNPN devices in a TO220 type package designed for general purpose high current applications where moderate gate sensitivity is required.

Application The IC regulates an input voltage VI in the range of 5.5 V < VI < 40 V to a nominal output voltage of VQ = 5.0 V. A reset signal is generated for an output voltage of VQ < VRT (typ. 4.5 V). The reset delay can be set with an external capacitor. The device has two logic inputs. A voltage of VE2 > 4.0 V given to the E2-pin (e.g. by ignition) turns the device on. Depending on the voltage on pin E6 the IC may be hold in active-state even if VE2 goes to low level. This makes it simple to implement a self-holding circuit without external components. When the device is turned off, the output voltage drops to 0 V and current consumption tends towards 0 μA.
