AN78L12M
3-pin positive output voltage regulator (100 mA type)
Overview
The AN78LxxM series are 3-pin, fixed positive output type monolithic voltage regulators.
Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components.
12 types of fixed output voltage are available; 4 V, 5 V, 6 V, 7 V, 8 V, 9 0 V12 V, 15 V, 18 V, 20 V and 24 V.
They can be used widely in power circuits with current capacity of up t0 mA.
The AN78L12M is the 12 V output voltage type in these series.

equipment, communications equipment, measuring instruments and household appliances).
Consult our sales staff in advance for information on the following applications:
– Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support
systems and safety devices) in which exceptional quality and reliability requied, or if the failure or malfunction of the prod-
ucts may directly jeopardize life or harm the human body.
– Any applications other than the standard applications intended.
(4) The products and product specifications described in this book are subjet to change wit notice for modification and/or im-
provement. At the final stage of your design, purchasingr use of the roducts, therfor the most up-to-date Product
Standards in advance to make sure that the latest specifictions stisfy your requirements.
(5) When designing your equipment, comply with he ange f absolute maximing nd the guaranteed operating conditions
(operating power supply voltage and operating nvirent etc.). Especiall, plee be ceful not to exceed the range of absolute
maximum rating on the transient state, such as powpower-off and modeswitching. Otherwise, we will not be liable for any
defect which may arise later in your equpmen
Even when the products are used withthe guaanteed values, kinto he cosideration of incidence of break down and failure
mode, possible to occur to semiconductor products. Measures on the sytems such as redundant design, arresting the spread of fire
or preventing glitch are recommin ordto prevent physicinjury, fre, social damaes, for example, by using the products.
(6) Comply with the instructios for se in rder to prevent breakdwn and characteristics change due to external factors (ESD, EOS,
thermal stress and mechanicastress) at the time of andlig, mounting or at customer's process. When using products for which
damp-proof packinis reqired, stisfy the condtions, sch as shelf life and the elapsed time since first opening the packages.
